This three-shelf utility cart is great for stocking and hauling heavy items. The spacious tub shelves are 2.5 inch deep to securely contain an assortment of items and at only 18 inch wide, the cart still leaves plenty of room for other traffic in narrow aisles. Made from high-density polyethylene plastic, the cart wont dent, rust, scratch, or stain and can hold up to 400 lbs. The industrial 5 inch semi-pneumatic casters are puncture resistant and provide shock absorption and quiet operation while an ergonomic handle make the cart easy to maneuver.
