Add secure storage and turn your 4-foot DeWalt rack into a functional workbench with the DXST4500WTD Work Top Drawer Kit. Designed to mount directly to the uprights of your existing 4-foot industrial storage rack using the same 2.35-inch adjustable tab system as the shelf crossbeams， this rugged accessory brings 120-pounds worth of additional secure storage capacity for tools and items to your rack along with a smooth-topped work surface that can support up to 1000-pounds on its own. Opening along smooth gliding ball bearing drawer slides， its interior measures 41-inches wide， 5.5-inches high and 18-inches deep - big enough to store everything from power and hand tools， to 3-foot sledge hammers and pry bars. Made of durable steel it has an industrial grade powder-coated finish that won't fade or chip like paint. Fits both the DEWALT DXST4500 and DXST4500-W Industrial Storage Racks (sold separately). To further prevent tipping that can be caused by a top-heavy storage shelf， floor-mounting anchors (part number DXSTA04MP) are also available.
