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, directly connected to the hardened deadbolt. The integrated design eliminates the traditional weak link between chain and separate padlock, significantly increasing structural integrity against brutal break-in attempts. The disc-style cylinder is technically refined for increased resistance to lockpicking and drilling, while the weather-resistant nylon cover prevents scratches on the frame. With a Security Rating of 5/10, this chain offers a flexible security solution ideal for quick-stop scenarios and as a secondary security in urban areas. This high-security chain lock from Kryptonite combines maximum protection with clever design. The 7 mm 3T manganese steel links resist sawing and cutting, while the patented end-link design and hardened deadbolt provide additional security. The disc cylinder is resistant to lockpicking and drilling, and the weather-resistant nylon cover prevents scratches. Two ergonomic "I"-keys and the Key Safe program ensure convenience and peace of mind. With 120 cm length and 1.7 kg weight, this chain offers top security in a compact form.7 mm 3T manganese steelPatented end-link designHardened deadbolt lockAnti-pick & anti-drill cylinderWeather-resistant nylon coverKryptonite Article Number: 740073 EAN code: 720018001706 Supplier number: 001706 Retail packaging: Yes
