ASP replacement locksets for Ultra and previous generation ASP handcuffs. These are not compatible with the new ASP Ultra Plus handcuffs with finger activated double locks. The replacement locksets allow you to replace damaged ASP locks or convert your current handcuffs. ASP locksets are easily removable and are interchangeable with chain, hinged, or rigid ASP handcuffs. You can convert standard handcuffs into high security or 3 pawl, etc. The locksets are color coded for easy identification. Standard 1 pawl locks are yellow (ASP81237). High security locks that require a special key are blue (ASP81238). European 3 Pawl are green (ASP81239) and use a standard handcuff key. Sold per each- you need 2 locksets to convert 1 pair of handcuffs. Keys not included. THESE DO NOT WORK FOR ULTRA PLUS OR SENTRY HANDCUFFS.
