Wire file cart offers two tiers of mobile filing to organize projects anywhere in your office. Letter-size folders can be placed in two rows for front-to-back filing or one lengthwise row on each file frame. The bottom shelf can be used for storage if additional filing is not needed. File frames accommodate both letter-size & legal-size hanging file folders. Wire cart is made of sturdy steel construction with a scratch-resistant, powder-coat finish. Two of the four swivel casters lock so you can secure the cart by your desk or file cabinet with no concern of it rolling away.
