This Luxor LP42CLE-B 3-shelf plastic AV cart is a great solution to storing and transporting projectors, document cameras, and all of your other AV equipment! The molded plastic shelves will not scratch, dent, rust, or stain, so you can feel confident that this cart will look good and perform well wherever you want to use it. Between the three shelves and the cabinet, the cart has a 400 lb. weight capacity when the weight is evenly distributed. Even when heavily laden, this cart will roll easily on its four heavy duty 4" casters, two of which have locking brakes to prevent the cart from rolling away when left alone.
