The ASP Sentry Handcuffs are a unique and high-quality addition to any law enforcement officer's gear. These handcuffs are constructed with a rigid, I-beam-inspired frame made from corrosion-resistant stainless steel with a unique, bead-blasted finish. The dimensional profile of the double bars delivers strength without unnecessary bulk, making them comfortable to carry and use. With a precision roller bearing pivot and forged steel bow, these handcuffs feature a smooth, hitch-free swing. ASP has eliminated sharp edges and rough surfaces found on traditional stamped steel cuffs, mitigating potential harm to suspects and reducing liability claims.The Sentry Cuffs also incorporate several operational features exclusive to A.S.P.'s top-of-the-line Ultra Cuff restraint family, including dual-sided keyways and double lock slots, speeding up applications and removals. The heat-treated steel bows also have flat contact areas for more precise and safe application. You can release the double lock and the bow with a single-direction key turn. This feature also facilitates easy "loosen and lock" adjustments.
