Merchandise concepts that really work. This time tested shelving system effectively merchandises clothing, giftware, appliances, sporting goods, hardware, and food products. Measures 72" high, 48" wide, and 18" deep from front to back. Heavy-duty chrome finish with rolling casters (with two locking wheels). The wire shelves allow light to penetrate through for better merchandise visibility, and minimizes dust buildup. Shelves adjust in 1" increments. Super strong, each shelf holds approx 200 lbs. Assembly is quick and easy�. No tools or hardware necessary. Snap split sleeves onto post at desired height. Then slide tapered shelf corners over sleeves, and it locks into place. Just reverse the steps to adjust or remove shelves.
