Magnetic bookends attach securely to metal desks, credenzas or shelves - ensuring that your reference materials stay put. The nonmar, nonslip protective pads will not damage surfaces. Perfect for housing binders, magazines and manuals, these magnetic bookends are made of heavy-gauge steel to provide maximum strength and stability. Steel is coated with a scratch-resistant, chip-resistant, powder-coat finish. The bookends' smooth edges prevent cuts when loading heavy materials.
