Chain lock Kryptonite Keeper 712 Black 1200 mm Steel 1.7 kg
The Kryptonite Keeper 712 Black is a steel chain lock designed for secure fastening of bicycles and other portable valuables. At 1200 mm in length and with a 7 mm diameter chain, it balances portability and resistance. The lock weighs approximately 1.7 kg, providing substantial mass that increases cut resistance while remaining manageable for everyday urban use.
The steel construction and compact, 1200 mm length provide a combination of strength and flexibility for wrapping around frames, wheels, and fixed objects. The 7 mm chain links and the overall weight contribute to mechanical robustness and increased difficulty for opportunistic cutting attempts. The black finish offers a discreet appearance and corrosion resistance suitable for outdoor use.
Wrap the chain around the bicycle frame and a fixed, immovable object such as a bike rack or sturdy post, ensuring the lock engages through both the frame and, if possible, a wheel. Close the shackle or lock body according to the manufacturer’s instructions and confirm the mechanism latches securely. When carrying the lock, secure it to the frame or store it in a bag to prevent rattling and wear.
For optimal security, use the chain lock in combination with a secondary locking device to secure both the frame and wheels. Choose well-lit, busy areas for parking and avoid leaving the bicycle unattended for extended periods. Regularly inspect the chain and locking mechanism for signs of corrosion or damage and lubricate the lock cylinder periodically with a graphite- or silicone-based lubricant recommended for locks.
