The Cuff Caliper is a calibration device designed to indicate the diameter of a pair of handcuffs or other restraint device.  The Cuff Caliper enables the user to easily identify the position of the restraint. The calibration scale is lasered on both sides of the cuffs.  The Cuff Caliper does not interfere with the mechanical workings or integrity of the handcuff. For more information on Cuff Calipers click here.
