Abstract
A tread support device for stairways is generally triangular with two parts which pivot in relationship to one another to allow selection of any desired riser height. Precalculated groups of holes on each of the two parts overlap, with different sets of holes overlapping at different riser heights separated by different increments of ⅛ inch. An alignment guide allows easy selection of the desired riser height, after which the holes which are aligned and overlapping are fastened together to keep the device whole. A complete system consists of left-handed and right-handed tread support units, along with right and left handed units designed to meet the base of the steps with adjustable bolts. A stairway may be built using uncut stringers by use of the invention.
