ASP makes duty batons and handcuffs for law enforcement and security professionals, best known for the expandable baton that made the brand's name a generic term for the category. Founded in 1976 by Dr. Kevin Parsons, a police academy instructor, and based in Appleton, Wisconsin, Armament Systems and Procedures set out to give officers better tactical tools alongside the training to use them responsibly. Its batons became so widespread that "ASP" is often used for any telescoping baton, and the company's gear is now carried by officers in more than 100 countries.

This category covers ASP's expandable batons and its handcuffs, including the Sentry and Ultra Cuff restraint lines. The Ultra Cuff family is ASP's top-tier restraint, while Sentry cuffs bring many of the same operational features to a more accessible price. Both baton and cuff models are made to ride on a duty belt in a dedicated baton case or handcuff case.

ASP's focus is duty tools engineered to exacting standards. Its expandable batons come in a range of lengths, weights, shaft materials, and finishes so an officer can match one to the assignment, and they deploy fast from a compact belt carrier. On the restraint side, Ultra Cuffs introduced features to a category that had been static for a century — dual-sided keyways and double-lock slots that speed application and removal, with the Ultra Plus adding keyless double locking. Sentry handcuffs carry those same dual-keyway and double-lock features in an I-beam stainless frame with a forged bow and roller-bearing pivot for a smooth swing, putting the operational advantages of the Ultra line within reach at lower cost. Chain, hinge, and rigid versions each trade mobility against control.
