Calipers are one of the oldest type of comparison measuring tools. These are designed for taking comparative measurements and transferring the dimensions to a micrometer, precision rule etc.Dividers are used for marking out circles on steel or transferring measurement from master templates. Manufactured from selected steel, calipers.The legs pivot on a roller and are tensioned by bow spring. The fulcrum stud has a large bearing surface that prevents side deflection of legs.Adjustment is made by opening and closing of the legs by means of an adjusting nut. Divider points are hardened 50-55 HRC for increased wear resistance.
