Includes cleats which mount with screws for hanging a packout box on any wall, plus a latch to hold the lock in place.
I mount all my packouts in my trailer using 2 cleats for narrow and 4 for wide, regardless of weight (they are all screwed to solid plywood). Most of my packouts are mounted with the latch facing up so I don't use the locks on them. For packouts mounted sideways or horizontally, locks are recommended.
