The Luxor Heavy-Duty AV Cart offers three 2"-thick shelves with a retaining lip to keep contents contained, and are made from molded plastic that won't stain, scratch, dent or rust. Strong construction and four 4" heavy-duty casters (with two locking brakes) enable the cart to support and transport up to 300 lbs. evenly distributed. The top shelf has a molded push handle for greater control as well as an integrated three-outlet UL-Listed electrical assembly for convenient power access. An adjustable-height pullout shelf is ideal for use as a keyboard or laptop tray.
