Works In Most Standard Cuffs, April 7, 2016 By Philip (Birmingham, AL)
One thing to keep in mind is that Safariland/Hiatt keys have a wider bit width that most, "standard," handcuff keys because the Safariland/Hiatt cuffs use the triple pawl design.
This key turned (snugly, but without force) in my Smith & Wesson, American Handcuff Co, and Peerless handcuffs. The key worked perfectly in my Hiatt-Thompson cuffs.
The key would not turn in some cuffs with a smaller single strand arms such as the Winchester and Chicago cuffs.
The double lock tip is long enough for any cuff I have come across. The design and construction of this key is great for a pocket key ring without taking up too much space on the ring (it is flat) while still providing that extended key feel.
