Kit of parts for trimming step edges

Apparatus for trimming a step edge for example a tread of a staircase, a step at an edge of a sunken floor, or a top edge of a short wall, comprising:

• a vertical riser board meeting a horizontal existing surface at or adjacent an edge of the existing surface;
• a facing material covering the riser board;
• an elongate member forming a nose piece above the facing material for mounting at the edge of the existing surface, the member having:
• a vertical rear surface along the riser board;
• a front face defining an attractive face that is opposite the rear surface;
• a horizontal top surface extending between the rear surface and the front face;
• an upper edge at a junction of the top surface and the front face;
• a lower edge at a bottom of the front face along the facing material;
• a continuously longitudinally extending groove in the front face of the member, the groove having:
• a base recessed from the front face;
• a first side edge in the front face of the member at a position spaced from the upper edge of the member and a second side edge on said front face at a spaced position from the upper edge of the member but farther therefrom than the first side edge;
• a first side wall extending from the base to the first side edge and a second side wall extending from the base to the second side edge;
• and
• a series of screws in the groove at spaced positions along the base thereof;
• the screws fastening the member in a mounted position in which the top surface of the member is spaced above the existing surface such that a thickness of a covering material which is disposed on the existing surface for covering the existing surface is located between the top surface of the member and the existing surface.
