The Rigid Ultra Cuff features a unibody frame that minimizes subject mobility. The frame is contoured to provide the officer with a proper, natural tactical grip for rapid application, as well as the ability to maintain control and compliance once the restraint is applied. ASP's exclusive Ultra Cuffs represent the most significant advances in restraint design in more than a century. These handcuffs were designed, tested, revised, re-tested and perfected in the field, with input from officers and tactical instructors around the world. The result is a restraint system with materials, construction and a feature set that simply can't be found in any other handcuffs.
