Sturdy rack holds twice as many books as most racks in the same amount of space. The 12-1/2" high bottom shelf holds magazines and catalogs. The top shelf is open for even greater height. A closed back prevents books from sliding off the desk or credenza. Two-tier book rack is made of heavy-gauge steel to provide maximum strength and stability. Heavy-duty, steel construction is coated with chip and scratch-resistant finish. Nonslip, nonmar pads protect desk or credenza.
