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.
