Checkers’™ wheel chocks were engineered in collaboration with safety experts to work with a wide range of ground equipment, commercial, and military vehicles. Whether you are chocking a fully-loaded 400-ton haul truck or a small utility trailer, we have the wheel chocks you need to safely secure your vehicle and meet compliance standards.
Our chocks have been field-tested under various conditions to ensure they 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 Checkers™ 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).
