Designed for law enforcement and corrections use, the Hiatt double-lock keyhole handcuffs set the standard for strength and reliability. The Model 2010HD handcuffs have keyholes on both sides of the cuff, so there is always one facing up, making the cuffs much easier to remove. Crafted from heavy-duty high carbon steel with a nickel finish, they have reinforced steel swivels that make them a rugged and secure choice for criminal justice professionals.
