Rugged, reliable, and spacious, this cart has three 2.75"-deep tubs to hold and haul larger supply quantities. Tubs are made from a durable thermoplastic resin that's resistant to scratching, dents, stains, and rust. Even when holding its max capacity of 133 lbs. per shelf, evenly distributed, the four 4" heavy-duty casters and a push handle molded into the top shelf help you smoothly move the cart; two locking brakes help keep it firmly in place when desired.
