Multi-Height AV Cart - Three Shelves. Versatility meets durability with the Multi-Height AV Cart, offering multiple leg sets to construct a 16"H two-shelf cart or a three-shelf cart up to 41"H capable of transporting 400 lbs. All three 1.5"-thick shelves, with a .25" retaining lip to secure items in place, are made from a molded plastic that will not scratch, dent, rust or stain. This cart is easy to maneuver thanks to four 4" heavy-duty casters and a push handle molded into the top shelf. A three-outlet UL-Listed electrical assembly with 15' cord and cord management system maintain a professional, organized look.
