Wheel Chocks
Keep wheels stationary while loading, unloading, and servicing vehicles. Chocks for wheel diameters 30" and larger are typically used for commercial vehicles, including semi-trucks and tractors. Chocks for wheel diameters under 30" are for use on small cars, trucks, and vans.
Reversible chocks can be used on both sides for twice the service life.
Rubber chocks are flexible with a high-friction surface, but wear more quickly than other materials. Aluminum chocks are lightweight for easy handling. Steel chocks are wear resistant for a long service life. Polyurethane chocks are lightweight and resist chemicals and oils.
Style 3 has multiple layers of laminated rubber to absorb shock.
Style 8 has a flag that inserts and locks on either side to indicate that chock is in use.
Chocks with a rope, carrying handle, or U-bolt handle give you a gripping point for easy carrying.
Chocks with a hole, an anchor plate with hole, an eyebolt, or a chain let you connect two chocks or can be secured to prevent theft.
Chocks with an antislip or serrated surface improve traction between wheels and the chock.
Chocks with a hollow middle are lighter in weight than solid chocks.
Chocks with reflective sides or a glow-in-the-dark strip are easy to see at night.

Pallet Truck Wheel Chocks


Keep pallet trucks upright and in place with these wheel chocks. They’re often used to stop pallet trucks from rolling while being transported, which prevents damage to the vehicle and the pallet truck. Since tipping pallet trucks on their side can cause hydraulic fluid to leak, these wheel chocks hold them upright.
Roll your wheels up the tapered side and into the recess, which keeps them from moving. Use the handle on the other side to carry the chocks, or to hang them for storage. Made of rubber, they’re durable and won’t slip.

Light Duty Wheel Chocks with Magnet


Stick these wheel chocks onto pallet trucks, carts, and other metal surfaces to keep them handy when they’re not in use—there’s a magnet on the base. Often used during deliveries, they keep light vehicles from rolling away while you load and unload.

Recycled Plastic Wheel Chocks


A sustainable alternative to standard plastic wheel chocks, these chocks are made from 100% recycled plastic, conserving manufacturing energy and resources. They keep wheels from moving while you load, unload, or service a vehicle. All have at least one hole, so you can tie two chocks together with a rope or attach a chain to secure the chock.
Nonreversible chocks only have one usable side.
Reversible chocks last longer than nonreversible chocks. When one side wears out, you can use the other side.

Wheel Chock Holders



Store wheel chocks near docks and loading zones so they’re on hand when vehicles arrive.
Style A and B holders have a wide top opening so you can easily pull out your wheel chock. They also have openings on each side to accommodate chocks that have eye bolts or chains on the ends. Style B holders have a sign reminding drivers to chock their wheels.
Style C holders have a narrow top opening for a tight fit and a support bar on the bottom to keep wheel chocks from falling through. They’re often mounted to vehicles because they’ll keep chocks from jostling and falling out during movement.
Wheel Chocks with Extended-Length Handle





Quickly and safely secure a vehicle’s wheels without bending down. The handle makes these wheel chocks ergonomic and reduces the risk of injury if your vehicle moves during installation. Use them during loading, unloading, and servicing vehicles.
Rubber chocks are flexible, so they have good traction to stop rolling wheels. However, they wear more quickly than metal chocks. Aluminum chocks are lightweight for easy handling. They also resist corrosion, so they’re suited for outdoor use. Steel chocks are wear resistant for a long service life.
Chocks with a flag increase visibility for safety. Chocks with a chain can be easily secured when not in use. Chocks with a hollow middle are lighter and easier to transport than solid chocks.

Railcar Wheel Chocks






Chock the wheels on stationary railcars to keep them from moving during loading, unloading, and servicing. They’re for chocking railcars on a flat track, so they’re not recommended for use on tracks at an incline or decline. Chocks install quickly, without tools.
A flag indicates that chocks are in use.
Single chocks prevent forward motion.
Double chocks prevent forward and backward motion. Painted steel chocks are connected by a chain; a rubber strap attaches to the chain and draws the chocks together. Polyurethane chocks won't degrade from corrosive chemicals, unlike steel chocks. They’re compressible, so they can expand back to their original shape. As a result, these chocks will not cause a spark or damage to the rail if a railcar runs them over. When you’re ready to remove them, pull the railcar over them before retrieving. They're connected by a cable, which weighs less than a chain and won't corrode from moisture.

Railcar Wheel Stops


Stop moving railcars at track ends and as they approach buildings and doors.
Foldable wheel stops swing down to the outside of the rail when not in use. You’ll need a left and right stop for a complete pair. They come with a padlock to keep them in the upright or lowered position, preventing unauthorized use. Bolt these stops onto your rail after drilling four 1 1/16″ holes into the rail web.
Nonfoldable wheel stops clamp to a rail, so no drilling is required for installation.

Railcar Stoppers

Bring slow-moving railcars to a halt. These stoppers have a chock at the end of a handle that you can place and remove in front of a wheel several times to absorb its momentum. They can hold a wheel in place until you install a permanent chock. After you’ve positioned a car with a railcar mover, they’re great for stopping it at an exact location. Use them to guide railcars to scale checks, repair shops, and loading zones. These stoppers are for use on flat track only.

Tire Locks
Stop forklifts, tuggers, and other vehicles from moving. The hardened steel construction on these locks make them difficult to cut or tamper with. They’re powder coated to prevent corrosion from rain and snow, so don’t worry about leaving them outside. They have a plastic cover to keep water and debris out of the key cylinder or combination digits, so they won’t freeze, corrode, or jam.
Style A locks secure all types of trucks and trailers. They wrap tightly around a wheel to prevent rolling.
Style B locks secure warehouse forklifts with solid rubber tires, electric scissor lifts, and forklift platforms. They’re not for use on pneumatic tires.
Choose keyed alike locks if you need several locks that open with the same key. Choose keyed differently locks if you need locks that each open with a different key. Resettable combination locks are good for multiple users because you can reset the combination at any time.
