COMMAND. Made to Play Hard. Sir Richard's Cuff & Collar Set delivers a strong statement. It allows the neck to be firmly secured along with both wrists, if desired. A sturdy, comfortable Heavy-Duty Collar wraps the neck, while two Heavy-Duty Cuffs wrap each wrist with thick, durable industrial-strength nylon straps that feature fully adjustable stainless steel lock rings, allowing for a controlled, custom fit every time.
