The Jeep JL Security Deck Enclosure creates a large and lockable storage area. The lid secures shut using Tuffy's patented security system working in conjunction with the Jeep's 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 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. 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.
