RaceQuip® SFI-approved arm restraints for racers driving an open cockpit car. Manufactured using high-grade steel hardware with premium polypropylene webbing utilizing hook-and-loop fastening. The design of these SFI 3.3 certified arm restraints uses 2 in. webbing for the cuffs and 1 in. webbing for the tethers that are attached to the cuffs. Cuffs are adjustable from 10-15 inches and the tethers adjust in length out to 20 inches to accomodate most adult racers. The steel ring at the end of the tether is designed to slide over the shoulder harness end link so that the arm restraints release with the belts.
