  • Patent number: 7322121
    Abstract: A device for checking the chamfer and/or radius of a corner of an object includes a housing having a pair of right angled surfaces at one end thereof for placement against right angled surface of the corner of the object having a chamfer or radius extending between the right angled surfaces. A sensing slide bar having a known angled distal end is slidably mounted in the housing and extends outward from the housing and is engageable with the chamfer or radius. The length of the outward extension of the slide bar is measured by a microprocessor in the housing and provides a digital display on the housing with a readout correlating to the chamfer or radius of the object's corner contacted by the angled distal end of the slide bar.
