Thanks to heavy-duty 5" casters (two fixed and two full-swivel with locking brake), this durable utility cart holds and transports up to 500 lbs. Its two flat shelves are 1.625"-thick, made of an injection-molded thermoplastic that won't stain, scratch, dent or rust, and have 25" of clearance between them providing easy access to items. And a handle that's molded into the top shelf provides greater control when maneuvering the cart from place to place.
