RRB Systems USA's Rapid-Cuff uses a standard Smith and Wesson handcuff for its metal guts and adds to it a nylon grip to turn the old chain link restraint device into a formidable tool for subject custody and control. Placed in the Safety Security Holster, the Rapid-Cuff can be rapidly drawn and used in a variety of ways. Cut down on incidents of resistance by using the Rapid-Cuff. A slight twist of the hand grip and the subject is quickly taken under control. Use it for escorts, ground stabilization, transports and general handcuffing. The newest model also contains a built in 'black box' feature, specifically designed for corrections personnel.
