Chain Combination

A Chinese invention, this single chain with four locks along it's length can be used as handcuffs, leg irons, neck chain, etc.. Multiple ones can be attached to each other as well, to increase use. E.g. two of these make a great wrist and ankle 4-way combination. The bolts at each end of the chain fit and are held by latches in any of the four barel locks. Which lock is used, along with which ring, determins what function they are serving. They are easy to apply and quite sturdy and functional. A bit unconventional in look, as a restraining device, to be sure.
