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 loose items. Plus, with more than two feet of clearance, it's easy to access what's below. Up top, there's a large flat 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. And a great utility cart needs great mobility, which heavy-duty swiveling casters provide (two with locking brakes).
