Single-Tier Lockers are ideal for schools, industrial facilities and office settings. Heavy-gauge steel construction and extra-strong five-knuckle hinges with secured hinge-pins help ensure rigid, reliable, long-lasting performance. Vertical louvers provide excellent ventilation. Inset handle design allows padlocks to be recessed to keep them from protruding into aisles and hallways. Door closing noise is effectively dampened with carefully placed bumpers. Multiple locker units can be ganged together into rows using standard nuts and bolts (additional units and ganging-hardware sold separately).
