The chain lock BC 380 is an all-rounder amongst the TRELOCK chain locks: with a length of 85 cm it offers sufficient locking range to connect the bike to a stationary object, the 7 mm thick chain links provide good theft protection in relation to the weight. The flexible hardened steel chain is protected by a resistant textile sleeve. In order to protect the wafer style cylinder from dirt, a dust protection cap is integrated in the lock head. The two included keys can be easily reordered (with the key number).
