Wheel Chocks prevent accidents during parking, vehicle storage or loading and unloading with hand trucks or powered vehicles. Wedging firmly against the wheels of vehicles, wheel chocks prevent the chance for inertia to cause rolling vehicles and trailer creep. Our chocks are most commonly purchased for loading docks, parked vehicles, motorhomes and RVs. All our wheel chocks are OSHA compliant, well designed and made of durable materials that make for a safer work place. See below for our full

*Please note* All wheel chocks we carry are available in kits with wall bracket, chain, sign and chocks. Chocks can be ordered with chains by themselves, but wall brackets and signage must be purchased together with chocks and chain.

Types of Chocks
- Kits (includes wall bracket, sign, chain and chocks)
- Rubber (heavy-duty and standard models)
- Aluminum (non-sparking and light weight)
- Metal (heavy chocks that perform on ice)
- Urethane (safety orange, light weight and chemically resistant)

Points to consider
Three main points to consider when selecting for your work area are below:
- Angle of the parking surface, called slope orgrade: Parking on a slope of ten degrees or greater increases the risk of the vehicle coming off or rolling over the chock creating a hazard.
- Size selection chock height compared to wheel height. As above, too small a chock will increase chance of roll.
- Surface friction or slip, performance can be impacted by the surface it rests on. Wet grass or ice can cause sliding. Increasing of size will not necessary allow the parking on inclines greater than 30% gradient (16.6 degrees).
Points to consider
Grit, grip and surface conditions are also something to consider. Loading areas, gravel driveways or areas prone to ground softening should have a chock that can dig in or has a size and weight to compensate for soft ground. Ice is also a factor. We carry chocks especially designed for icy conditions. See the Ice chock IC-10 model in safety Yellow.
SELECTING YOUR WHEEL CHOCKS
Size Selection
Proper size selection is one of the most important aspects to keep in mind. A general rule is height of the chock should be approximately 1/6 to 1/4 the height of the wheel height. For areas with steep slopes or grade larger chocks should be used or in instances where manufacturer or local requirements are higher. Things like vehicle weight, load weight and surface friction may change the requirements. Always base your specifications on your specific working area and note what has worked in the past.
Chemical and Flammable Hazards
Loading docks or storage areas handling hazardous or flammable chemicals may have special requirements. Urethane is a good fit here. Chocks have different properties and being aware of what is best for your work area is key. Aluminum chocks are anti-sparking. While urethane chocks are resistance to chemical interaction. Always use your companies’ best practices and consult your industries regulations. See above for product selection sorted by material.
