Mobile Locker Safe keeps your valuables and electronics secure—even when you're on the go! Heavy-duty plastic safe has an attached 5' steel cable that can be tethered to a heavy object (like your vehicle or a tree) for extra protection. You can even charge your electronics while they're in the safe—just run charging cords through two access holes in the back. Set your own combination to the built-in, four-digit combination lock. Safe has reinforced corners and side rails and an ID card window on door. Includes removable shelf. Locker is 14" w x 12 1/2" h x 18" d.
