The black thermoplastic cover gives the Tessi Lock 40M Outdoor a weather-proofing, making it an ideal lock for side gates and sheds. When used with a sheathed chain, the plastic cover will also prevent any damage to paintwork if it runs against the body of a bike. Each lock is equipped with an 8mm hardened steel, double-locking shackle, making it resistant to cutting and prying. The lock is available in a 40M size and comes in a black color.
