The DEWALT DXST4500-W is a 4 Foot Tall, 3 Shelf Industrial Rack designed and engineered to provide heavy-duty storage for both professional and home use. This rack features innovative details that aren't typically found on industrial racks such as dense wire grids, safety straps with weld nuts for ease of assembly, and top caps that protect both you and your items from possible damage. The three industrial metal wire grids can each support 1,500 lb. evenly distributed for a total of 4,500 lb. That is two and a quarter tons of storage and organizing capacity. The uprights, crossbeams, and support straps are all made from powder-coated steel and are designed so that once assembled, each shelf has two types of support straps in addition to the crossbeams to prevent them from buckling under pressure. The shelves are adjustable in 2.35-inch increments and the locking pins ensure that each shelf is properly installed. The rack has glass-filled nylon feet so it will not damage flooring and a wall mount bracket so you can secure your rack in place to prevent tipping. With the double row design of the uprights, each rack also includes 2 stacking plates so you can securely join two racks together vertically or horizontally to create a complete storage solution customized for your needs. For easy assembly, two of the four uprights come with pre-installed horizontal and diagonal support beams which makes getting started fast. In addition to the standard hex key and wrench tool, a hex bit has been included to use with your favorite DEWALT driver so you'll be in, out, and organized in no time.
