Garb Tie Downs can be attached to the rack and are left on or are easily taken on and off. Attaching to the rack at each side is faster than any other type of strap. By adjusting the buckles (once) to firmly hold your boat(s), the tie down can be used like a customized bungie cord. Extremely durable and UV treated. Garb Tie Downs are fast, secure and hassle free. Two per set.
