ABSTRACT:
A returned stair tread for use on an open stairway or an open portion of a stairway is shown. This returned stair tread comprises a stair tread constructed of wood and a return nosing fitting flush against its side edge, the stair tread and nosing being slidably connected to one another by tongue and groove construction. The returned stair tread also comprises means for securing the nosing to the stair tread, including rigid securing means joining the nosing to the stair tread only in the region containing an exposed joint located at a forward end portion of the tread forward of the slidably connected construction. The returned stair tread further comprises a non-rigid securing means joining the nosing to the stair tread along the length of their mutual juncture, which non-rigid securing means is adapted to secure the continued contact of the nosing and stair tread while permitting each to expand and contract in width over a range due to changing ambient temperature and humidity conditions.
