The name comes from our high security 3-point turn-handle latching mechanism that includes 3/8'' diameter locking rods and a 3/16'' thick locking plate. Lockers are of all-welded construction providing a lifetime of user satisfaction. In addition to the welded-in fixed upper shelf, coat rod and coat hooks, lockers will accommodate optional adjustable shelves so you can customize this locker to meet your specific storage requirements. While these lockers make excellent wardrobe storage lockers, they are so heavy-duty that they can handle the rugged uses of manufacturing, military and law enforcement personnel. These lockers combine maximum door strength by adding a welded-in full-height door stiffener to a super-duty 14 gauge outer door providing a rigid, torque-free door. Locks are not included. Heavy 16 gauge body with 18 gauge back makes these lockers the industry's best. Lockers are available in two models, a ventilated model with diamond perforated doors and sides and a solid model. Doors include a continuous piano hinge to insure worry-free door operation. Locks are not included. SecurityMax welded lockers ship fully-assembled in 1-wide units. Color: Light Gray.
