Designed for group lockout applications, this patented design features eight key positions inside, and twenty-seven lock positions on the outside of the box. All keys used to lock power sources are placed inside the box. All people working on the equipment place their locks on the outside of the box. Molded in high impact-resistant LEXAN(®) polycarbonate, the group lockout box has a high-visibility yellow body and a clear front which allows all people working on the equipment to see that the power sources are locked. The group lockout box measures 11H x 12-1/2W x 4D".
