Abstract
A stariway can be constructed by using movable tread/riser supports placed along a stairway stringer and the supports can be moved as a group or individually to accomodate a stairway slope of any desired degree. It is desirable to mark a stringer for the uniform equal spacing of the location for the tread/risers and to establish the pivot positions for mounting the supports on the stringer. The present invention is an apparatus that will permit a user to locate the desired pivot holes equally spaced and aligned along a stringer.
