The ASP Black Aluminum 3 Pawl Hinge Handcuffs (Green - European) provide a major advance in both the design and construction of wrist restraints. Its frame geometry is the result of extensive computer modeling and simulation analysis. The strength potential of this product has been maximized through use of an interlocking, unitized frame. The structure of this cuff is forged from high strength aluminum on custom built, high speed, progressive dies. Each restraint is then overmolded with ordnance grade polymer under 75 tons of pressure. The flat bow section provides single movement application preventing slippage on wrist. The Lock Assembly is unitized and replaceable, it incorporate a 4 point aluminum connection. The rivetless exterior design allows the cuffs to lie flat in a case or on the belt. The restraints provide increased control of the most resistant subjects.
