The Jeep JL Security Deck Enclosure creates a large and lockable storage area. The lid secures shut using Tuffys patented security system working in conjunction with the Jeeps locking tailgate. The lid easily hinges open and can be held up using an attached support rod. The lid, vertical front and side panels can be easily removed without tools so larger items can be transported when required. The entire Tuffy Deck Enclosure is constructed using welded 16 gauge steel, heavy duty fasteners, and covered with a durable textured powder coat finish. The Tuffy Deck Enclosure does not rely on the wheel well to create an enclosed space adding an additional level of security. The patented design, quickly and easily installs to the vehicle floor with standard hand tools in the 4 door model with and without an OEM hardtop. It functions with the OEM compartment cover and has access built to in for the OEM wheel well power supply. The vehicle power lock switches on the tailgate become disabled after approximately 16 seconds when locking the doors with the key fob so the enclosure remains secured. Any items stowed on top of the deck enclosure must be securely fastened to the vehicle. Tuffy anchor rails sold separately. No drilling required. Mounting brackets are fastened to existing OEM mounting points in the vehicle floor. The side panels are fastened to the mounting brackets and joined by the front panel with quick hand operated knob screws. The top then inserts into the side panels and can be rotated open when the tailgate is open and supported using the attached prop. The top, front and sides can be easily removed without tools.
