The CTS Thompson Model 9010 cuffs are oversized for handcuffs, almost comparable to leg irons in scale (if a bit lighter). These handcuffs are stainless steel with a nickel plating. The inside perimeter opens to 8"-10.75", allowing for larger wrists or padding. The distance between cuffs is 2 1/2" allowing for some motion while restricting any motions that are too extravagant. These cuffs weigh in at 14.6 oz. 2 handcuff keys included. CTS Thompson Cuffs are made in the USA.
