This California approved Remington Cable Lock features a hardened steel laminated lock body for extra strength, Ball-Lock cable retaining system and brass 4 pin tumbler lock plug. Wire cable is protected by hardened steel beads offering flexibility with extra protection against cutting and sawing. The Remington Cable Lock is an improvement over some of the "rack and gear" designs, which require the need to hold the cable in place while turning the key engaging the rack and securing the cable..
