This heavy-duty utility cart has two spacious flat shelves that are more than 1.5" thick and one 2.5" deep bottom tub shelf. Made from tough thermoplastic resin that won't stain, scratch, dent or rust, the three shelves can hold up to 500 lbs. (evenly distributed). A push handle that's molded into the top shelf and heavy-duty 5" casters (two fixed and two full-swivel with locking brake) make this rolling cart easy to move when you want and easy to secure when you don't.
