The original ASP Ultra Cuffs set a new standard in restraint design, technology, features and application. Now Ultra Plus Cuffs raise the bar again, with the addition of a major new feature: keyless double locking. Double locking-a critical step in ensuring both subject and officer safety-is accomplished simply and instantly, just by pressing the double lock bar with a fingertip. The bar is color-indicated, for quick visual status recognition-once cuffs are applied and set, if you see the indicator, press it. This makes the process faster, easier and less likely to be skipped or overlooked. And because a key no longer needs to be accessed or present during the cuffing process, it's even safer for all involved.
