Checkers has been protecting people and assets since 1987 as a leading manufacturer of cable protection systems, wheel chocks, warning whips, warning lights, and more. With over 25 years of experience, Checkers third-party tests and certifies most of our products.
Checkers Wheel Chocks have been field-tested by expert 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). Thorough testing must be completed at each location by users to ensure that specific wheel chocks will meet your specific chocking requirements.
