The wheel chocks are 7-1/2” high x 9” Long with a high friction base for improved locking grip. These wheel Chocks are a rugged design yet light-weight and easy to position/remove. An optional 18’ zinc plated chain to secure wheel chock to dock area is available. A optional single or double wall bracket (not shown) is available for ease of storage when the wheel chock is not in use.
