This large utility cart offers the best of both worlds. A lower tub shelf that's 4" deep securely contains contents such as cleaning supplies, heavy objects or other item, and with more than two feet of clearance, items are very accessible. There's a large flat top shelf with a retaining lip for items that need to be more readily available great for stocking and inventory. Both shelves are made from a tough thermoplastic resin that won't scratch, stain or rust and they can collectively hold up to 400 lbs. When fully loaded, the cart is still easy to maneuver thanks to heavy-duty 4" full-swivel casters (two with locking brakes).
