Three flat shelves make this the perfect utility cart for any applications. Each shelf has a 0.25" retaining lip to help keep contents from sliding off, and the cart''s injection- molded thermoplastic resin won''t scratch, dent or rust. Even when fully loaded with up to 300 lbs., an integrated push handle and heavy-duty 4" casters make it easy to transport items down the hall, across carpet or over cracks and cables on the floor.
