Jumbo storage cabinet features heavy-gauge steel throughout for maximum rigidity. Extra-wide doors move on four heavy-duty leaf-hinges. Three-point locking system ensures secure storage for bulky materials. Simply turn the handle and doors lock at three points for maximum security. Nylon guides help make operation quiet. Two brushed chrome handles, with one that locks both doors, easily open and close the dual swing-out doors. Cabinet base offers a "box" construction technique to prevent racking. Integrated levelers compensate for uneven or warped floors. Storage cabinet also includes four shelves, hardware, top for cabinet and bottom for cabinet. Adjust shelves in 2" increments without tools. Shelves, cabinet top and cabinet bottom are made of heavy-gauge steel and engineered with box-formed reinforcement construction to accommodate the larger 48" width, allowing up to 400 lb. of weight per shelf.
