"The Phoenix Police Department has adopted the ASP Sentry Chain Handcuff as its new standard-issue restraint following an evaluation that began in 2024.
The approximately 2,400-officer department evaluated replacement restraints through its defensive tactics division. Officer Shane Merwin led testing of the Sentry Cuffs, which were ultimately approved by Phoenix Police Chief Matt Giordano.
According to the department’s evaluation, officers found the ASP restraints offered improvements over their previously issued handcuffs. The agency cited smooth and precise operation, handling characteristics, safety and overall quality."
