A stair component has foundation member including a nose end. Upon attachment of the component to a stair, the nose end projects outwardly from an upper forward edge of the stair. The nose end has a substantially uniform cross-sectional configuration along substantially its entire width. A nose cover having an ornamental exterior surface overlies and covers substantially the entire nose end. The nose cover comprises a thin continuous sheet of preformed plastic having first and second substantially parallel planar portions joined by a curved portion. The foundation member, which may be constructed on site or formed off-site, is adapted to be positioned (a) directly next to a riser portion of the stair so that a vertical support element of the foundation member abuts the riser portion or (b) indirectly so that the vertical support element abuts a secondary vertical member disposed between the foundation member and the riser portion. |
