Master Lock Company's covered solid brass padlocks are designed for indoor and outdoor use. Master Lock's corrosion-resistant, high-security solid brass padlock is combined with a protective vinyl cover. The cover prevents scratching and marring and the keys also feature vinyl covers for easy identification and use. The lock cover comes in black. The lock features a pin-tumbler lock mechanism to resist picking, and a dual-locking system which independently locks each shackle leg to prevent pulling, prying and hammering.
