The measuring gage has a body which is positioned in the upright direction for vertical measurement or can be positioned in any direction for other measurements. The body includes a notched land area for nesting a ruler which is locked in by rotatable stops to restrict ruler movement. A further recessed area within the ruler land area houses a strip magnet to hold the ruler. Two half-round configurations simulate vertical rods which serve as ways upon which the measuring arm and protractor housing ride. A T-shaped slot between the half-round rod ways acts to retain a nut for the measuring arm. The measuring arm can glide along the body and measure the height directly against the ruler. The magnetic strip retains the ruler in its nested area when the gage body is in a vertical position and unsecured by the cam locks.
