Metal Wall Lock Box is made of durable, powder-coated steel with key slot on top and includes clear Lexan window that slides out when locks are removed. Includes key pegs and ID labels to simplify key management, and predrilled holes and hardware for quick mounting. Use one lock on each energy control point and place the keys in the lockout box;each worker then places his own lock on the box to prevent access. Each employee retains exclusive control, as required by OSHA, by placing his own lock on the lockout box containing the keys to the job locks. As long as any one worker's lock remains on the lockout box, the keys to the job locks contained inside cannot be accessed.
