Mount this group lockout box on a wall, or carry it with you as a portable solution for storing keys used to secure padlocks to lockout points.
Completely secure once installed, the Master Lock 503 lockout box includes a slot for inserting keys; it doesn't even have to be opened to insert them! With Master Lock's exclusive Latch Tight technology included as standard, it's also impossible to actually open the box before the very last padlock is removed.
The Master Lock 503 lockout box has integrated storage for organisation of up to 12 keys, or hundreds of bulk keys. On the exterior, up to 14 workers can apply their own personal safety padlock, or it's possible to expand the number of padlocks by using lockout hasps (sold separately).
