ASP Hinge Handcuffs 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.
