Maximize your visibility. All-purpose chests sit below the bedrail accommodating tonneau covers and lids. The model 665-5-01 steel full size chest features a black Armor-Tuf® powder coat finish that ensures years of dependability and has a storage capacity of 13.1 cu ft. The cover opens to 90 degree for maximum access using a unique offset hinge design that still allows installation flush against the truck cab. The rotary-style latch mechanism keeps the cover tight against the weather seal and provides smooth one touch opening.
