Holding tires up to 5.5" wide, the Deluxe Chrome Motorcycle Wheel Chock from Extreme Max Products provides an elegant design with a rugged stability and the convenience of being quickly removable. Constructed from reliable chrome-plated steel tubing, this wheel chock is strong enough to hold all your heavy-duty applications. The mounting system incorporates the use of tee nuts and two mounting brackets, making for a fast, tool-free assembly and takedown (after initial installation), keeping your floor clear when the chock is not needed. Specifications: Height: 9" Interior Width: 5.75" Total Length: 12" Note: The Deluxe Chrome Motorcycle Wheel Chock is not intended as an unassisted stand for your motorcycle; straps are required for safely securing your motorcycle and are not included. The chock MUST be mounted to a solid surface for safe use. The included mounting hardware allows installation on surfaces no thicker than 1.25". For thicker surfaces, additional mounting hardware is required.
