What is a Chock?
A chock is a small block which is positioned underneath a wheel to prevent it from rolling. Chocks are used to secure vehicles of all shapes and sizes, and they are a common site at garages and other facilities where wheeled vehicles are routinely handled. The term “chock” may also be used to describe a support which holds a structure such as a barrel in place. These blocks are designed in a wedge shape, with the thin point of the wedge facing the wheel, and the thick part facing outwards. The wedge is installed against the side which is most likely to roll, which can be based on the incline at which a vehicle is parked, the gear the vehicle is left in, or the vehicle’s design. Chocks are also known as “wedges,” in a reference to their shape. They can be made from plastic, wood, rubber, metal, and other materials, and they are often attached to a length of line so that they can be pulled away quickly. The rope or line also keeps the chocks firmly tethered so that they do not wander off
