The extra-secure chain lock in our CORVID K range is virtually noiseless yet incredibly sturdy with a tear-resistant, hard-wearing textile sleeve. With 360° of rotation, the EASY ENTRY lock body is incredibly simple to use, while the protective cap keeps the lock mechanism protected against water and dirt ingress. The CONE+ closure reduces the risk of theft further and makes locking and unlocking a cinch. GRIP+ surface technology ensures maximum grip. A rubberised surface prevents corrosion and protects your frame against scratches.
