30" Rubber Wear Strip for the TracRac Overhead Rack crossbars. Insert the wear strip into the crossbar T-Slot, it will protect your crossbar from wear caused by ladder and material loading. Manufacturer's part number: RX-12007-1
This product was disappointing. It doesnt cover the width of the rack like I feel it needs to and was too short side to side to adequately protect the metal frame from damage when placing materials on top. Im still looking for a better solution but it will do for the time being.
