Abstract

A cantilever stair assembly for installation in segments or sections includes a stair tread module including a stair tread plate having a tread hole. An embedded stair tread is inserted into and fixed within the tread hole. The stair tread module may include a first inner wall stair tread support and a second inner wall stair tread support for mounting to opposite sides of a vertical support member. Each of the first and second inner wall stair tread supports has a first plate with a plurality of support-member-engagement holes therethrough and a second plate perpendicular to the first plate and having a plurality of stair-tread-plate-engagement holes therethrough. The stair tread plate is secured to at least one of the plurality of stair-tread-plate-engagement holes of each of the first and second inner wall stair tread supports.
