Make the most of your truck bed space with BEDBINS, from Bedslide. The BEDBIN Upper Tray Kit adds an additional 16 x 48 bin that mounts above any Bedslide with a GUARDRAIL or TRAXRAIL kit. The upper BEDBIN provides added storage space for smaller items while still providing full use of your Bedslide deck space. With your new upper BEDBIN you sit at 15 ½” off the floor of the truck bed allowing you space for items in the bin and still sliding all your items right under a tonneau cover. Made in the USA with high quality aluminum, composite materials, and an all weather soft surface in the bin. For use of the upper BEDBIN with side BEDBINS be sure to measure your rail length.
