Master Lock Padlock 30mm Diamond Brass Keyed Different is a solid brass padlock for securing gates, sheds, lockers and equipment. The brass body is strong, durable and resists corrosion, which suits outdoor and exposed positions. A hardened steel shackle provides extra resistance to cutting and sawing, the 4-pin cylinder resists picking, and dual locking levers provide resistance against prying and hammering. Keyed different, so each lock operates on its own key rather than sharing one across a set. Supplied with two keys and covered by a Limited Lifetime Warranty.
