3 Shelf, Heavy Duty Boltless Shelving, Add On, 48"W x 12"D x 72"H, No 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. Front-to-back supports help prevent beams from rotating when fully loaded. Double Rivet button stud construction locks perimeter beams into corner post forming a structurally secure joint, eliminating back and side sway. Each add on unit includes rugged 14 ga steel T Posts that are punched on 1 1/2" centers and double riveted horizontal beams that adjust vertically on 1 1/2" increments. Chip resistant Gray baked enamel finish. Order decking separately.
