Set of two 4M/13FT heavy duty woven 3cm nylon straps, attached to spring-loaded weather-resistant sleeved metal cam locks. When applied correctly, enjoy peace of mind that Surftech auto strap systems securely maintain appropriate tension even at freeway speeds during transportation. For best results in securing a board to your vehicle or rack, Surftech recommends that after looping the strap through the cam lock and adjusting to appropriate tension, tie a knot in the strap behind the cam lock. Does not include auto rack pads. See Description tab below for more application and safety info.
