Go Rhino Trunk Trays come standard with over 900 square inches of workable space on the full width tray and plenty of area for mounting a variety of electronic equipment. The Trays slide on ball bearing tracks offering a stable platform extension with a positive locking latch preventing the tray from moving under heavy acceleration. Optional mounting boxes further simplify installation of electronic equipment. Trunk Trays are made from heavy duty 12 gauge steel with a textured powder coat finish for durability.
