This, heavy-duty multipurpose cart allows you to support and transport up to 300 lbs. All three shelves offer a .25" retaining lip to secure items in place and are made of high-density polyethylene plastic that won't scratch, dent, rust or stain. The middle and bottom shelves offer 14" and 17.75" of clearance respectively, providing ample space for important cargo. The molded push handle built into the top shelf provides greater control when moving the cart while four 4" heavy-duty, full-swivel casters with two locking brakes provide easy maneuverability.
