The BEDBIN deck divider adds an additional 7 in. x 44 in. bin that can be placed in any position on the deck of the BEDSLIDE. The deck divider sits loose on the BEDSLIDE but has a non skid pad allowing you to wedge items in 1 location. Keep groceries towards the front of your BEDSLIDE or hold items from shifting side to side. The deck divider also doubles as a BEDBIN for storing smaller items.
