ABSTRACT:
A lever-actuated dial gauge supported above a workpiece by a base block. The lever includes a pedal portion which, when parallel to the workpiece, has a working clearance beneath it. When setting the height of machine tools above a workpiece, an operator may exceed the set point clearance without making a hard contact and thereby preventing damage to the machine tool.
