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, progressive dies. Each restraint is then overmolded with ordnance grade polymer under 75 tons of pressure. The Lock Assembly is unitized and replaceable.
