New from Hiatt: Hiatt Model 2010-HD Standard Nickel Chain Handcuffs with keyholes on both sides of handcuffs. You won't have to worry about finding the keyhole side of cuffs. Other than the extra keyholes, they are the same as standard Hiatt 2010 handcuffs. They have 18 teeth on swinging bows, 3 pawls that move independently and must be depressed simultaneously to release, and backloading for fast handcuffing. Heavy duty construction and oversized rivet heads make them an ideal choice for challenging applications. Double locks at sides. 2 keys included.
