The Master Lock 1.8m Self Coiling Combination Cable is designed for securing bicycles and outdoor equipment. This security cable features a 4-digit resettable combination mechanism, allowing users to set their own code for keyless convenience. The cable is constructed with an 8mm diameter core and is encased in a protective vinyl covering, which helps prevent scratching on bicycle frames and other surfaces. The self-coiling design assists with compact storage and transport when not in use.
