The Master Lock box, built by the lock company you trust for safety and security. These Master Lock boxes are crafted as strong and rugged as you’d expect from a Master lock box, with a solid die-cast body that holds up to 5 conventional keys and hangs from a door knob or railing. Protective cover on shackle resists scratches, and the molded bumper protects surfaces. This Master lock box has the combination code preset to 0-0-0-0, but you can set your own combination, and change it at any time. Master lock boxes give you more code options than a 3-digit lock box.
