Kryptonite keeper 712 chain with integrated combination lock – bicycle chain lock – electric bicycle lock – 120 cm – steel – black

The Kryptonite Keeper 712 Integrated Chain (720018001706) is a 120 cm long chain lock configuration with 7 mm thick links made of 3T manganese steel, connected directly to the hardened deadbolt shackle. The integrated design eliminates the traditional weak link between chain and loose padlock, significantly increasing structural integrity during brutal break-in attempts. The disc-style cylinder is technically refined for increased resistance to lockpicking and drilling, while the weatherproof nylon cover prevents scratches to the frame. With a Security Rating of 5/10, this chain offers a flexible security solution that is ideal for quick-stop scenarios and as secondary security in urban areas.
