The Master Lock shackle lock with a loop at the end and 11 cm wide, extra robust hardened steel housing offers maximum security. The 28 cm long double shackle made of hardened steel with a diameter of 16 mm resists cutting tools, saws and attempts to break it open. The disc locking cylinder prevents the lock from being picked. A 1.2 m long cable with a diameter of 10 mm and loops at the end provides additional security.
