Abstract: A combined distance and gradient gauging device is disclosed, including a base member, and at least one arm member slideably connected with said base member for parallel longitudinal displacement between collapsed and fully extended positions relative thereto, respectively, characterized in that the arm member is manually displaceable between a plurality of predetermined longitudinally displaced intermediate positions, relative to the base member so that the remote end extremities of the base and arm members are spaced at corresponding predetermined gauge distances, respectively.
