Rubber Wheel Chocks are a low cost, effective way of preventing unexpected movement of vehicles.
Chocking, also known as blocking, is done to prevent aircraft, trucks, trailers and other vehicles from unintentionally moving. This is especially important to prevent rolling or overturning, while workers are loading, unloading, hitching, unhitching or servicing the vehicles. Unintentional movement is a scary and dangerous situation. It can cause injury and in some cases death.
