Since hinged handcuffs permit less movement than a chain cuff, they are generally considered to be more secure. Hinged cuffs can be used one-handed to apply pain-compliance/control techniques that are not workable with the chain type of cuff.ASP Aluminum Hinge Handcuffs with Tactical Security or European Pawl will provide increased control of violent subjects. Because of their conical bow geometry, the cuffs fit large subjects, yet still control small wrists. They are easily carried, rapidly applied and have a clean, smooth, finished appearance. The four point connection system allows the cuffs to fold flat and yet be worn over belts of various thicknesses. Because connecting rivets are integral with the side plate, they cannot be driven out.As with all ASP products, the design for these Hinge Handcuffs originated in the field. ASP Trainers surveyed instructors and officers throughout the world. The most desirable handcuff features were listed and categorized. The result is a handcuff unlike any other. The design introduces features, construction and materials that are innovative, real world and strong.An optimized frame design was achieved through the use of sophisticated computerized engineering programs. Strength potential was maximized through an optimal combination of materials, heat treatment, frame geometry and reinforcing ribs. The over-molded stainless steel frames of ASP Hinge Handcuffs flex to the side when improperly applied to reduce injury potential from excessive lateral stress.The swivel has traditionally been the weakest part of any handcuff design. The Hinge cuff uses a pin and plate link to provide rigid frame alignment. The stainless steel links of ASP Hinge Handcuffs have a four point pivot structure to maximize handling characteristics.The Tactical ASP Handcuffs feature a replaceable Lock SetAluminum handcuffs weigh 15% less than steel models and are distinguished by their black bows.
