Checkers® wheel chocks comply with the safety requirements of a variety of industries and ensure a safe working environment while your vehicles are at rest. Offered in a variety of styles, our wheel chocks provide a safe chocking solution for any type of vehicle.
Checkers® wheel chocks were engineered in collaboration with safety experts to work with a wide range of ground equipment and commercial vehicles. Whether you are chocking a fully loaded 400-ton haul truck or a utility trailer, we have the wheel chocks you need to safely secure your vehicle and meet compliance standards.
Wheel chocks have been field-tested by expert Checkers™ team members under various conditions to prove our products prevent non-motorized, uncontrolled movement of on and off-road vehicles. Checkers™ has also worked with a third-party laboratory to certify that each model meets the specifications indicated on the Checkers™ Wheel Chock Reference Guide. Specific models of our wheel chocks meet specifications required by MSHA (Mine Safety and Health Administration), OSHA (Occupational Safety and Health Administration), SAE (Society of Automotive Engineers), NFPA (National Fire Protection Agency), and the DOT (Department of Transportation).
