KryptoLok 915 five foot heavy duty chain

Updated 2026-09-05

This five-foot chain lock features 9.5 mm four-sided links made from hardened manganese steel for reliable bicycle protection. The extra-long design is perfect for securing a bike to large trees, light poles, or multiple bikes together. A protective nylon cover is included to prevent the steel links from damaging the bicycle's paint or frame.

The lock head is integrated into the chain and features a hardened deadbolt that resists prying and twisting. A high-security disc-style cylinder provides resistance against picking and drilling, ensuring the lock remains secure in various environments. This design offers a streamlined locking experience without the hassle of managing a separate padlock and chain.

Two ergonomic keys are included, providing a simple and effective way to secure the bike. The five-foot length makes it one of the most versatile options for riders who frequently encounter non-standard locking situations. Its durable construction and weather-resistant materials make it a long-lasting investment for any cyclist concerned about security.
