4 Shelf, Commercial Duty Boltless Shelving, Add On, 48"W x 24"D x 60"H, Wire Deck

Easy set-up with snap-in components. No nuts, bolts, or clips required. Make expansion easy and join units with more stability and less construction than bolting 2 starter units together. Sturdy roll-formed steel framing provides maximum support. Top and bottom shelves use Double Rivet button stud construction to lock perimeter beams into corner post forming a structurally secure joint, eliminating back and side sway. Center shelf uses Single Rivet beams. Each add on unit includes rugged 14 ga steel T Posts that are punched on 1 1/2" centers, double riveted horizontal beams, and single rivet horizontal beams that adjust vertically on 1 1/2" increments. Chip resistant Gray baked enamel finish. Wire decking allows ventilation, visibility and light penetration. Sprinkler water passes throughout racks easily, improving fire safety and lowering insurance premiums.
