ASP Identifier Handcuffs provide a major advance in both the design and construction of wrist restraints. Frame Geometry is the result of extensive computer modeling and simulation analysis. Strength Potential has been maximized through use of an interlocking, unitized frame. The cuff structure is forged from high strength stainless steel on custom built, high speed pregressive dies. Each restraint is then overmolded with ordnance grade polymer under 75 tons of pressure. Identifier Chain and Hinge cuffs are produced in three tactical and three high visibility colors.
