Five-drawer steel Flat File offers a welded steel construction, wraparound corners and a sturdy inner frame for durable storage of important documents. Heavy-gauge steel with a powder-coat finish has front supports. Case-hardened ball-bearing rollers provide you with smooth, quiet operation. Positive closures keep your drawers tightly shut, while courtesy stops keep them in place while open. Keep contents clean with a rear. Modular design stacks up to five high on a closed base. Antislip pads fit between units to prevent shifting. Each unit can store up to 1,000 sheets. The closed base (sold separately) raises files 6" off floor.
