Similar to the model 11, but these are hinged in the center with a single piece of very thick steel. They too operate with a barrel key and feature a thumb activated double lock. This little manacle is not seen very often out there. It definitely has a "different" look. Type 19 R, hinged. With 18 locking positions to accommodate both large and small wrist sizes. Standard double locking mechanism. Heavy duty rivet. Fast, smooth, positive swing through action.Supply does include 2 keys
