EZY Wheels Shipping Container
EZY Wheels are a patented, bolt-on wheel-and-spindle system engineered by Container Nut™ to enable safe, crane-free repositioning of 20-foot and 40-foot ISO shipping containers. Each set locks into the container’s bottom corner castings via a twist-and-lock mechanism, converting a stationary steel box into a towable unit that can be maneuvered across yards, construction sites, and off-road terrain using a skid steer, telehandler, forklift, or pickup truck.
Moving a 12-meter-long (40-foot) steel box that weighs over 8,000 pounds empty has, for decades, meant one thing: calling a crane. But for container homeowners, construction site managers, storage yard operators, and off-grid builders, that reality changed dramatically with the arrival of purpose-built container wheel systems — and at the forefront of that shift stands the EZY Wheels shipping container mobility kit. This guide covers every dimension of the EZY Wheels system: how it works, where it came from, what it can and cannot do, and how it stacks up against every alternative on the market.
What Are EZY Wheels for Shipping Containers?
Definition and Core Concept
EZY Wheels are a pair of heavy-duty axle-and-spindle assemblies designed to attach to the bottom corner castings of an ISO shipping container. Each unit consists of a machined steel adapter body that terminates in a standard automotive-style hub — either 6-lug or 8-lug — onto which the user mounts wheels and tires of their choosing. The adapter body is engineered to slide into the oval opening of a container’s corner casting and lock in place with a 90-degree twist, creating a mechanical connection strong enough to bear the dynamic load of towing a multi-ton container across uneven ground.
Once both EZY Wheels are locked into the two rear corner castings (or the two front corner castings, depending on the direction of pull), the container is lifted at the wheeled end by a skid steer, telehandler, or forklift. The opposite end of the container remains on the ground or is supported by the lifting equipment. The operator then tows the container to its new position. Ratchet straps looped from each EZY Wheel to the top corner casting and back down prevent the adapters from rotating and accidentally unlocking during transport.
The system is fundamentally different from traditional shipping container casters. Where casters bolt or twist-lock into all four bottom corners and keep the container suspended on four swiveling or fixed wheels, EZY Wheels attach to only two corners — typically the rear pair — and rely on the lifting equipment to bear the load at the front end. This two-wheel configuration makes the system simpler, lighter, cheaper, and faster to deploy than a full four-caster setup, while still delivering the core benefit: crane-free container relocation.
The Brand Behind EZY Wheels: Container Nut
EZY Wheels are manufactured by Container Nut™, a company based in Washington, Missouri, that specializes in shipping container accessories, mobility solutions, and anchoring hardware. Container Nut is a SAM.gov-registered and CAGE Code–certified manufacturer, meaning it meets the U.S. federal government’s requirements for doing business as a defense and government contractor — a credential that speaks to the company’s manufacturing quality and traceability standards.
Container Nut’s product line extends beyond EZY Wheels to include the EZY Lift leveling system, Twist Nuts (fasteners for attaching accessories to corner castings), and various container anchoring and securing hardware. The company distributes through its own website (containernut.com), Amazon, eBay, and a network of authorized resellers including Box Shop Containers, Top Gun Storage Solutions, and Container Sales Group.
How EZY Wheels Fit Into the Broader Container Wheel Ecosystem
The term “shipping container wheels” is an umbrella category covering at least five distinct product types: swivel casters, fixed casters, end wheels, bolt-on spindle kits, and full undercarriage systems. EZY Wheels belong to the bolt-on spindle kit category — the simplest, most affordable, and most DIY-friendly segment of the market. They are positioned for the container owner who needs to move a container occasionally, across unpaved or semi-improved surfaces, without investing in a permanent wheeled chassis or a full set of professional casters.
How Do EZY Wheels Work?
The ISO Corner Casting Interface
Every shipping container manufactured since the late 1960s conforms to the ISO 1161 standard, which specifies, among other things, the dimensions and load-bearing characteristics of the corner castings — the steel blocks with oval openings located at all eight corners of the container. These castings measure approximately 7 × 6 × 4.5 inches (178 × 152 × 114 mm) and are designed to bear the entire weight of a loaded container, whether stacked nine-high on a ship, lifted by a spreader crane, or secured to a truck chassis.
The oval openings in the bottom face of each corner casting are the universal mounting point for every container wheel system on the market. EZY Wheels use these openings — specifically the pair at the rear (or front) of the container — as their sole attachment point. The adapter body of each EZY Wheel is machined with a profile that matches the corner casting’s oval aperture, so that when inserted and rotated 90 degrees, the adapter’s shoulders lock against the inside walls of the casting.
The Twist-and-Lock Mechanism
The twist-and-lock mechanism is elegantly simple. The EZY Wheel adapter features a T-shaped or lobed head machined from the same 1045 Cold Rolled Steel as the rest of the unit. When the adapter is oriented so that the head aligns with the oval opening, it slides into the corner casting. Rotating the entire adapter 90 degrees — by hand, before the wheel is attached — turns the head perpendicular to the oval opening, trapping it behind the casting’s internal shoulders. The adapter is now locked.
The twist-lock mechanism is the universal language of container handling. A 90-degree turn of a steel locking head inside the oval opening of a corner casting creates a mechanical connection rated for tens of thousands of pounds — no bolts, no welding, no permanent modifications to the container.
Because the lock relies on geometry rather than friction, it is inherently fail-safe in the vertical direction: the weight of the container pulling downward on the adapter only forces the locking head more firmly against the internal shoulders of the casting. The one vulnerability — and the reason ratchet straps are mandatory — is rotation. If the adapter were to rotate back 90 degrees during use, the locking head would realign with the oval opening and the wheel could fall out. This is exactly what the ratchet straps prevent.
The Role of Ratchet Straps
Ratchet straps are included with every EZY Wheels kit and are not optional. Each strap runs from a dedicated anchor point on the EZY Wheel adapter, up to the top corner casting of the container, and back down to the adapter. The strap is tensioned lightly — there is no significant load on it during normal operation — and its sole purpose is to prevent the adapter from rotating and unlocking if the container were to high-center (that is, if the bottom of the container were to catch on a mound, rock, or uneven ground, lifting the wheel off the ground momentarily). In that scenario, without the strap, the unloaded adapter could rotate freely and unlock. The strap keeps the adapter in its locked orientation regardless of what the container does.
What Is the History and Origin of EZY Wheels?
The Container Mobility Problem Before EZY Wheels
The intermodal shipping container was standardized in the late 1960s, but for the first several decades of the container era, the problem of moving containers on land — at the “last mile” of the container’s journey — was solved almost exclusively by cranes, tilt-bed trucks, and specialized container handlers. These solutions worked well for ports, rail yards, and logistics hubs, but they were expensive, inflexible, and overkill for the growing number of containers being used for non-shipping purposes.
By the 2000s, the container home movement had begun to take off. Architects, builders, and DIYers were buying retired shipping containers and converting them into houses, offices, workshops, and retail spaces. These users faced a problem that the logistics industry had never needed to solve: how to move a single container a few hundred feet across a residential property, a construction site, or a farm — without a $500-per-hour crane call.
The early solutions were improvised. Some users welded trailer axles directly to their containers, permanently altering the structure and voiding any structural warranty. Others used pipe rollers, come-along winches, and sheer manpower. Professional container casters existed — Tandemloc’s AC49000A series had been on the market since the 1980s — but they were priced for industrial buyers and designed for smooth warehouse floors, not dirt and gravel. The market was calling for a simpler, cheaper, more rugged solution.
The Founding of Container Nut and the EZY Wheels Innovation
Container Nut was founded in Washington, Missouri, by Jason Bailey, a shipping container industry veteran who recognized the gap between expensive professional caster systems and the unsafe DIY workarounds that container owners were resorting to. The EZY Wheels concept was born from a straightforward insight: container owners didn’t need a full four-wheel caster system that could swivel in any direction. They needed a simple, two-wheel axle system that would let them tow a container behind a skid steer or pickup truck in a straight line across dirt, gravel, and grass.
The first EZY Wheels were designed, prototyped, and tested in-house. The choice of 1045 Cold Rolled American Steel — a medium-carbon steel with excellent strength, machinability, and wear resistance — was deliberate. The nickel-chrome plating was chosen for corrosion resistance in outdoor environments. Robotic welding ensured consistency across every unit. The 6-lug and 8-lug hub options were offered so that customers could use wheels and tires they already owned or source cheaply from the used market.
Evolution of the Product Line
Since the initial launch, the EZY Wheels product line has expanded to include the EZY Lift leveling system, bundled kits with wheels and tires pre-mounted, and international shipping options. The product has been sold to customers in over a dozen countries, and the company reports thousands of units sold. Container Nut has also introduced the Twist Nut — a fastener that allows accessories to be bolted to corner castings — and has built a distribution network of authorized resellers.
What Are the Technical Specifications of EZY Wheels?
Weight Capacity and Load Ratings
The EZY Wheels system is rated for a Safe Working Load (SWL) of 8,800 lbs per set (two adapters). This rating covers the dynamic loads encountered during towing — acceleration, braking, cornering, and traversing uneven terrain. In practical terms, an 8,800-lb SWL means the system can safely handle:
- An empty 20-foot shipping container (tare weight approximately 5,000 lbs)
- An empty 40-foot shipping container (tare weight approximately 8,000–8,500 lbs)
- A 20-foot container with a modest amount of contents (up to roughly 3,800 lbs of cargo)
- A 40-foot container with minimal contents
Important: EZY Wheels are not rated for towing a fully loaded shipping container. A loaded 40-foot container can weigh up to 67,200 lbs — more than seven times the system’s SWL. Attempting to move a loaded container with EZY Wheels risks catastrophic failure, injury, and property damage.
Materials and Construction
| Specification | Detail |
|---|---|
| Adapter Body Material | Grade 1045 Cold Rolled American Steel |
| Hub Material | Grade 1045 Cold Rolled Steel |
| Welding | Robotic MIG welding |
| Finish | Nickel-chrome electroplating |
| Hub Type | Pre-assembled with lug studs and nuts |
| Manufacturing Location | Washington, Missouri, USA |
| Certifications | SAM.gov registered, CAGE Code certified |
The choice of 1045 steel is significant. Unlike lower-carbon steels (such as 1018 or A36), 1045 offers a higher tensile strength and yield strength, making it suitable for components that experience cyclic loading. Unlike higher-carbon steels, it retains enough ductility to withstand impact without brittle fracture. The nickel-chrome plating provides a hard, corrosion-resistant surface that outperforms standard zinc galvanizing in outdoor exposure.
Dimensions, Ground Clearance, and Fitment
| Dimension | Measurement |
|---|---|
| Ground clearance (with standard tires) | Approximately 12 inches |
| Lateral extension past container | Approximately 12 inches (tire-dependent) |
| Adapter weight (per unit) | Approximately 37.5 lbs |
| Shipping dimensions (per box) | 24 × 16 × 8 inches |
| Shipping weight (per box) | 75 lbs |
Ground clearance is adjustable by tire size. Users who need maximum clearance for rough terrain can mount larger-diameter tires — old mud-terrain truck tires are a popular choice — which increases clearance and improves flotation on soft ground. The 12-inch lateral extension past the container wall is important for users with tight clearances; the wheels protrude noticeably beyond the container’s footprint.
What Is the Difference Between 6-Lug and 8-Lug EZY Wheels?
EZY Wheels are available in two hub configurations: 6-lug and 8-lug. The two variants are functionally identical in terms of load rating and intended use. The difference exists solely to give customers flexibility in sourcing wheels and tires.
| Feature | 6-Lug EZY Wheels | 8-Lug EZY Wheels |
|---|---|---|
| Lug Pattern | 6 × 5.5 inches | 8 × 6.5 inches |
| Center Bore | 3.5 inches | Varies (check before purchase) |
| Safe Working Load | 8,800 lbs per set | 8,800 lbs per set |
| Common Wheel Sources | Chevrolet/GMC half-ton trucks, Jeep, older SUVs | Many older 3/4-ton and 1-ton trucks, some trailers |
| Wheel Availability | Extremely common, wide aftermarket | Common, but check bolt pattern carefully |
| Tire Options | Extensive — standard truck tires, all-terrain, mud-terrain | Extensive — heavy-duty truck tires, all-terrain, mud-terrain |
| Price (adapter only) | ~$549.99 | Comparable pricing |
| Best For | Users who already own 6-lug wheels or want the widest used-market options | Users who already own 8-lug wheels or want to use heavier-duty tires |
Lug Pattern and Compatibility
The 6-lug variant uses a 6 × 5.5-inch bolt pattern — the same pattern used by Chevrolet and GMC half-ton trucks (C/K 1500 series), many Jeep models, older Toyota trucks, and countless aftermarket trailer hubs. The 3.5-inch center bore is the critical dimension: the wheel’s center hole must be at least 3.5 inches in diameter to fit over the EZY Wheels hub. Some aftermarket wheels with smaller center bores will not fit.
The 8-lug variant uses an 8 × 6.5-inch bolt pattern, common on older Ford, Chevrolet, and Dodge 3/4-ton and 1-ton trucks, as well as many utility and equipment trailers. Users are advised to source wheels first and confirm the center bore diameter before purchasing the EZY Wheels adapters, or to buy the adapters first and then source wheels that are confirmed to fit.
Which Variant Is Right for You?
If you do not already own a set of wheels and tires you intend to use, the 6-lug variant is generally the more practical choice. The 6 × 5.5 pattern is one of the most ubiquitous bolt patterns in North America, and used wheels in this pattern are plentiful and inexpensive. The 8-lug variant makes sense if you already have a set of 8-lug wheels, or if you want to run heavy-duty 10-ply (Load Range E) tires for maximum puncture resistance on rough terrain.
How Do You Install EZY Wheels on a Shipping Container?
Required Equipment and Tools
| Item | Purpose |
|---|---|
| Skid steer, telehandler, or forklift | Lifting the container |
| EZY Wheels kit (2 adapters, lug nuts, ratchet straps) | The wheel system |
| Wheels and tires (2) | Mounted to the hubs |
| Lug wrench or impact wrench | Tightening lug nuts |
| Heavy-duty ratchet straps (included) | Securing adapters against rotation |
Step-by-Step Installation Process
Step 1: Position the lifting equipment. Bring the skid steer, telehandler, or forklift to the end of the container you intend to lift. The wheeled end of the container will be the trailing end during towing, so attach the EZY Wheels to the end that will be farthest from the tow vehicle. For most configurations, this means attaching the wheels to the rear of the container.
Step 2: Mount the wheels and tires. Before attaching the adapters to the container, mount your chosen wheels and tires onto the hub assemblies. Use a lug wrench or impact wrench to tighten all lug nuts to the manufacturer’s specification. It is significantly easier to do this on the ground than after the adapter is locked into the corner casting.
Step 3: Insert the EZY Wheels into the corner castings. With the container still on the ground, orient each EZY Wheel adapter so that its locking head aligns with the oval opening in the bottom corner casting. Slide the adapter upward into the casting until the locking head is fully inside. Rotate the entire adapter 90 degrees. You should feel and hear the locking head engage behind the internal shoulders of the casting.
Step 4: Attach the ratchet straps. Loop one ratchet strap from the anchor point on each EZY Wheel adapter, up through the top corner casting (or around the top rail near the corner), and back down to the adapter. Tension the strap lightly — just enough to hold it taut. The strap is not load-bearing; it exists solely to prevent the adapter from rotating and unlocking.
Step 5: Lift the container. Insert the forks or lifting attachment into the fork pockets (if equipped) or under the bottom rail of the opposite end of the container. Lift slowly. As the container rises, the EZY Wheels will take the weight. Observe the adapters and straps to confirm everything is secure.
Step 6: Begin towing. With the container lifted at one end and rolling on the EZY Wheels at the other, proceed at low speed — walking pace or slower — to the destination. Avoid sudden stops, sharp turns, and uneven terrain that could cause the container to high-center.
Safety Precautions
- Never stand under a lifted container. If the container must be accessed from below, use proper jack stands rated for the load.
- Inspect the corner castings before installation. Castings that are damaged, deformed, or excessively corroded may not provide a secure lock.
- Confirm the ratchet straps are in place and taut before every move. A strap that has loosened or been forgotten can result in the adapter unlocking and the wheel detaching mid-tow.
- Use a spotter. A second person walking alongside the container can monitor the wheels, straps, and ground conditions while the operator focuses on the tow vehicle.
What Equipment Is Needed to Move a Container with EZY Wheels?
Compatible Tow Vehicles
EZY Wheels are designed to be towed by a range of common heavy equipment and vehicles:
| Vehicle Type | Suitability | Notes |
|---|---|---|
| Skid steer loader | Excellent | Most common choice. Compact, maneuverable, powerful. |
| Telehandler | Excellent | Longer reach, good for lifting the container higher. |
| Forklift | Good | Requires sufficient capacity and fork length. |
| Pickup truck | Conditional | Only on flat, firm ground. A 4WD truck with a tow hitch and low-range gearing is best. |
| ATV / UTV | Limited | Only for very short moves on hard, flat ground with an empty 20-foot container. |
| Tractor | Good | Farm tractors with a 3-point hitch or front loader work well on agricultural land. |
The skid steer is the most commonly used tow vehicle, and for good reason. Its compact footprint, powerful hydraulics, and ability to lift the front of the container while pushing or pulling make it the ideal partner for EZY Wheels. Container Nut’s own instructional videos consistently demonstrate the system with skid steers.
Surface and Terrain Considerations
EZY Wheels can operate on a variety of surfaces, but not all surfaces are equal:
| Surface | Suitability | Notes |
|---|---|---|
| Compacted gravel | Good | The most common use case. Works well with adequate tire footprint. |
| Dirt / grass | Good | Soft ground increases rolling resistance. Larger tires help. |
| Asphalt / concrete | Excellent | Lowest rolling resistance; easiest towing. |
| Loose sand | Poor | High risk of sinking and bogging. Not recommended. |
| Mud | Poor | Loss of traction and potential for getting stuck. |
| Steep slopes | Dangerous | Risk of runaway. Avoid grades steeper than 5–10%. |
Speed and Maneuvering Guidelines
EZY Wheels are designed for off-road use at walking speed or slower — typically no more than 2–3 mph. The system has no suspension, no brakes, and no steering geometry. Every bump, dip, and rock is transmitted directly through the rigid adapter to the container structure. Higher speeds dramatically increase the dynamic loads on the adapter, the corner casting, and the container itself, and reduce the operator’s ability to react to hazards.
Turns should be made gradually. The EZY Wheels are fixed-direction (non-swiveling), so sharp turns cause the tires to scrub sideways across the ground, which can stress the adapter, loosen the locking mechanism, and cause the container to tip if the turn is severe enough.
Can EZY Wheels Be Used on the Highway?
The Off-Road-Only Designation
No. EZY Wheels are categorically not designed, rated, or approved for highway use. Container Nut’s documentation, product listings, and FAQ responses are unequivocal on this point. The system lacks every feature required for road-legal towing: no suspension, no brakes, no lighting, no fenders, no DOT certification, and no speed rating.
“Can the EZY Wheels be used on the Highway? NO! NO! NO! They are not made for highway use. They are made for off road only and slow speeds.” — Container Nut FAQ
Legal and Safety Implications
Using EZY Wheels on a public road would violate multiple federal and state vehicle regulations, including lighting requirements, braking requirements, and equipment standards. In the event of an accident, the operator would face significant legal liability and would almost certainly be found at fault. Insurance policies would not cover damages resulting from the unauthorized use of off-road equipment on a public roadway.
The safety risks are equally stark. At highway speeds, the lack of suspension would subject the adapter and corner casting to impact loads far exceeding their design limits. The lack of brakes would mean the towing vehicle must handle the entire braking load of the container — a multi-ton unbraked trailer. The lack of a proper hitch system means there is no engineered breakaway mechanism. Any failure at speed would be catastrophic.
Alternatives for Highway Transport
If a container needs to be moved on public roads, the only legal and safe options are:
- A tilt-bed truck or rollback truck — the container is winched onto the bed and transported as cargo.
- A container chassis trailer — a purpose-built trailer with a twist-lock system that secures the container for road transport.
- A professional container transport company — the simplest and safest option for most container owners.
How Do EZY Wheels Compare to Other Container Wheel Systems?
EZY Wheels are one of several types of container mobility systems. The right choice depends on the user’s budget, frequency of use, surface conditions, and maneuvering requirements.
| System | Attachment | Steering | Capacity (set) | Surface | Price Range | Best For |
|---|---|---|---|---|---|---|
| EZY Wheels (bolt-on spindle kit) | Twist-lock into 2 bottom corner castings | Fixed | 8,800 lbs | Dirt, gravel, grass, asphalt | $550–$900 | Occasional moves, DIYers, container homes |
| Swivel casters | Twist-lock into 4 bottom corner castings | 360° swivel | 10,000–67,200 lbs | Smooth concrete, asphalt | $1,500–$10,000+ | Warehouses, depots, frequent repositioning |
| Fixed casters | Twist-lock into 4 bottom corner castings | Fixed | 10,000–67,200 lbs | Smooth concrete, asphalt | $1,000–$7,000 | Straight-line moves in yards and warehouses |
| End wheels | Pin through side corner casting holes | Fixed | 11,000–32,000 lbs | Concrete, asphalt, compacted gravel | $500–$1,500 | Simple, tool-free installation |
| Undercarriage systems | Twist-lock into 4 bottom corners + tow bar | Front steerable, rear towed | 28,000–60,000+ lbs | All surfaces | $3,000–$15,000+ | Daily industrial use, rough terrain |
| Hydraulic self-lifting | Twist-lock with integrated jacks | Various | 22,000–88,000 lbs | Rough terrain, unpaved | $2,000–$12,000 | No separate lifting equipment needed |
EZY Wheels vs Swivel Casters
Swivel casters (such as the Tandemloc AC49000A series) are the professional standard for warehouse and depot container handling. They attach to all four corners, keep the container fully suspended, and allow omnidirectional movement — critical for tight maneuvering between rows of stacked containers. They are also significantly more expensive, heavier, and require smooth, hard surfaces. EZY Wheels sacrifice the omnidirectional capability and the four-corner suspension in exchange for a dramatically lower price, simpler installation, and the ability to work on unpaved surfaces.
EZY Wheels vs End Wheels
End wheels (such as the ContainGo system) mount to the side holes of the corner castings rather than the bottom holes. This design keeps the wheeled end of the container closer to the ground, which can be an advantage for stability. However, end wheels also require a different lifting approach and typically have a lower load capacity than the EZY Wheels system. The two products serve similar markets and are often cross-shopped by container owners.
EZY Wheels vs Undercarriage Systems
Undercarriage systems are the closest thing to a “real” trailer for a shipping container. They include a steerable front axle, a tow bar, and a fixed rear axle, and can handle significantly higher loads and rougher terrain than any bolt-on spindle kit. They are also the most expensive option, costing several thousand dollars. For a container depot that moves containers daily, an undercarriage system is the right tool. For a container homeowner who moves a container once or twice a year, EZY Wheels are the more practical choice.

What’s Included in the Kit
A standard EZY Wheels kit includes:
- 2 EZY Wheel adapter/hub assemblies (pre-assembled, with lug nuts)
- 2 heavy-duty ratchet straps
- Instructions
Wheels and tires are not included in the base kit. The user must supply their own, either from their existing inventory, from the used market, or from a tire retailer. This is a deliberate design choice: it keeps the base price low and allows users to select tires optimized for their specific terrain — highway all-season tires for hard-packed surfaces, all-terrain tires for mixed use, or mud-terrain tires for soft ground and maximum clearance.
Shipping and International Availability
EZY Wheels are manufactured in the United States and ship free to the lower 48 states through most authorized retailers. International shipping is available — Container Nut reports regular shipments to overseas customers — but shipping costs are additional and must be quoted directly. The weight of the system (approximately 75 lbs per box) makes international shipping a significant expense.
What Are Common Misconceptions and Problems?
Highway Use Misconception
The most dangerous misconception about EZY Wheels is that they can be used for highway towing. They cannot. The system is engineered for off-road use at low speed only. Attempting highway towing with EZY Wheels is illegal, unsafe, and will void any warranty or insurance coverage.
Loaded Container Misconception
The 8,800-lb SWL is for the entire set — not per wheel. An empty 40-foot container weighs approximately 8,000–8,500 lbs, which is already close to the limit. While a small amount of additional cargo may be within the margin, the system is not designed to move loaded containers. EZY Wheels are a solution for moving empty containers.
“The Wheels Come Off” Concern
A concern sometimes voiced by first-time users is that the twist-and-lock mechanism seems too simple to be reliable — that the wheels might “pop out” during use. In practice, the geometry of the system makes this extremely unlikely when the ratchet straps are properly installed. The weight of the container pulls the adapter downward, forcing the locking head more firmly against the internal shoulders of the corner casting. The only scenario in which the adapter can unlock is if the container high-centers, lifting the wheel off the ground and removing the downward force — and the ratchet straps are specifically designed to prevent rotation in exactly that scenario.
Common Installation Mistakes
- Forgetting the ratchet straps. The single most common and dangerous mistake. Without straps, a high-center event can unlock the adapter.
- Using the wrong lug pattern. 6 × 5.5 and 8 × 6.5 are not interchangeable. Attempting to mount 6-lug wheels on an 8-lug hub (or vice versa) will damage the studs and the wheels.
- Ignoring center bore clearance. Some wheels with the correct bolt pattern may have a center bore smaller than 3.5 inches (6-lug) and will not seat properly on the hub.
- Over-tightening or under-tightening lug nuts. Follow the torque specification for the wheel and stud size. Over-tightening can stretch or snap studs; under-tightening can allow the wheel to work loose.
- Towing on a slope with inadequate tow vehicle. A container on EZY Wheels has no brakes. If the tow vehicle cannot hold the load on a slope, the container can run away.
Terrain Limitations
EZY Wheels are not all-terrain in the absolute sense. Loose sand, deep mud, and steep slopes are outside the system’s operating envelope. The rigid, unsuspended connection between wheel and container means that every rock, rut, and root is felt directly — and sharp impacts can damage the adapter, the corner casting, or the container structure. Users should assess the entire route before beginning a move and avoid any terrain that exceeds the system’s capabilities.
Frequently Asked Questions
What are EZY Wheels?
EZY Wheels are a bolt-on wheel-and-spindle system manufactured by Container Nut in Washington, Missouri. They attach to the bottom corner castings of a shipping container via a twist-and-lock mechanism, allowing the container to be towed by a skid steer, telehandler, or other heavy equipment across off-road terrain.
How much weight can EZY Wheels handle?
EZY Wheels are rated for a Safe Working Load (SWL) of 8,800 lbs per set. This is sufficient for an empty 20-foot or 40-foot shipping container. They are not rated for moving fully loaded containers.
Can I use EZY Wheels on the highway?
No. EZY Wheels are designed exclusively for off-road use at low speed. They lack the suspension, brakes, lighting, and DOT certification required for highway operation. Using them on public roads is illegal and dangerous.
What is the difference between 6-lug and 8-lug EZY Wheels?
Both variants have the same 8,800-lb SWL. The difference is in the bolt pattern: 6-lug uses a 6 × 5.5-inch pattern (common on half-ton trucks), while 8-lug uses an 8 × 6.5-inch pattern (common on 3/4-ton and 1-ton trucks). The choice depends on which wheels and tires the user has or intends to purchase.
How do I install EZY Wheels?
Lift the container with a skid steer or telehandler, insert the EZY Wheel adapters into the bottom corner castings of the container, rotate 90 degrees to lock, attach the ratchet straps from the adapters to the top corner castings and back, mount the wheels and tires, and begin towing at low speed.
Do I need ratchet straps?
Yes. The ratchet straps are included with every kit and are mandatory. They prevent the adapters from rotating and unlocking if the container high-centers during a move.
How much do EZY Wheels cost?
The 6-lug adapter kit (with ratchet straps) is priced at approximately $549.99. Bundles with wheels and tires range from $800 to $1,200. Shipping is free to the lower 48 states from most authorized retailers.
Are EZY Wheels made in the USA?
Yes. EZY Wheels are manufactured by Container Nut in Washington, Missouri, from Grade 1045 Cold Rolled American Steel. Container Nut is SAM.gov registered and CAGE Code certified.
Can EZY Wheels be used on a 40-foot shipping container?
Yes. EZY Wheels are designed for both 20-foot and 40-foot containers. The 8,800-lb SWL covers the tare weight of an empty 40-foot container (approximately 8,000–8,500 lbs).
What equipment do I need to move a container with EZY Wheels?
The most common tow vehicle is a skid steer loader. Telehandlers, forklifts with sufficient capacity, and farm tractors with front loaders also work well. Pickup trucks can be used on flat, firm ground with an empty 20-foot container, but are not recommended for larger containers or uneven terrain.
How long does installation take?
With the wheels and tires already mounted on the hubs, attaching the EZY Wheels to the container and securing the ratchet straps typically takes less than two minutes per side. The entire process — from positioning the lifting equipment to beginning the tow — can be completed in under 10 minutes.
Can I leave EZY Wheels on the container permanently?
EZY Wheels are designed to be attached for moving and removed for storage. Leaving them on the container permanently is not recommended, as the adapters are not designed for long-term static loading and the wheels and tires would be exposed to the elements. The container should be set down on blocks, a foundation, or the ground for long-term placement.

If you are researching the cost of a 20 foot shipping container, you have likely already encountered wildly different prices — from $999 listings online to quotes exceeding $5,500. That range is not a sign of inconsistency. It reflects real differences in container condition, location, delivery logistics, and the seller you are dealing with.
Side Opening container
A side opening container is an ISO-compliant intermodal shipping container engineered with full-length bi-fold doors along one of its long side walls, in addition to the standard cargo doors at one end. Unlike conventional containers that restrict access to a single set of rear doors, a side opening container — also widely called an open side container, open-sided shipping container, or side door container — provides unobstructed lateral access across the entire 20-foot or 40-foot length of the unit. This design transforms the container from a narrow tunnel into a wide-open space that forklifts can enter from the side, multiple workers can load simultaneously, and oversized cargo that would never fit through standard end doors can be placed without struggle.
40 Foot High Cube container cost
A 40 foot high cube container — often abbreviated as 40ft HC, 40′ HC, or 40-foot high cube — is one of the most common shipping container sizes sold on the secondary market. But if you are researching what a 40 foot high cube container costs, you have almost certainly noticed that prices are all over the map. One seller quotes $1,500. Another quotes $7,000. Both could be legitimate.
20 Foot container cost
If you have ever searched for a shipping container, you have almost certainly asked one question first: how much does a 20 foot container cost? The answer is not a single number. It is a range that spans from under $1,000 for a weathered, as-is unit to over $5,000 for a pristine, one-trip container — and that is before delivery, site preparation, or modifications enter the picture.
