The Smith & Wesson Model 1851 Oversized Transport Restraint is a set of leg and hand restraints that are connected by heavy duty chain. Composed of a pair of Model 110 handcuffs attached by a heavy duty 32" chain to a pair of Model 1900 leg irons, this transport set is very secure and reliable. This set is also a touch larger than the standard as far as the inner perimeter of the individual cuffs go, as this set uses the oversized models. 2 keys included. Weighs 50 ounces.
