Im not a police officer. I just used these for a costume to handcuff a briefcase to my wrist. They worked perfectly and seemed pretty solid. They did not come loose or show any signs of weakness for the entire night and I will be saving them and using them again if I ever want to handcuff a briefcase or suitcase to anything.
BEST Quality and service anywhere. We had to have handcuffs custom made to order. They were exactly what we needed and will last. True durability and quality. And MADE IN THE USA! I recommend purchasing whatever your handcuff and leg iron needs are, from this wonderful company.
