Kits of parts for trimming step edges

Apparatus for trimming a step edge comprising:

• a riser board for locating a top of the riser board disposed in upright orientation at or adjacent an edge of a substantially horizontal existing surface defining said step edge;
• an elongate member forming a nose piece for locating at the edge of the existing surface, the member including a top, a rear for facing towards the step edge, and a front ornamental face that is opposite the rear;
• a covering board for covering the existing surface;
• the covering board having a top wear surface, a bottom surface for facing the existing surface, a front edge for locating proximal the member, and a rear edge for locating distal to the member;
• the member being arrangeable in a mounted position in which the top of the member is spaced above the existing surface such that a thickness of the covering board is locatable between the top of the member and the existing surface;
• the member including a locking recess in the rear that is spaced from the top so as to leave an upper portion of the rear of the member between the recess and the top for locating at a height of the existing surface in the mounted position of the member;
• the locking recess having a base spaced inwardly from the rear of the member, a top sidewall extending from the base to the rear of the member, and a bottom sidewall opposite the top sidewall;
• and a fastener connected to the covering board and projecting forwardly from the front edge thereof at a location spaced below the top wear surface for cooperation with the locking recess to mechanically couple the covering board and the member;
• the fastener comprising:
• a base strip having a forward edge spaced forwardly from the front edge of the covering board and defining a surface of the base strip located generally between the forward edge of the base strip and the front edge of the covering board;
• and
• at least one deflectable projection upstanding from the surface of the base strip which can deflect relative to the base strip in at least a rearward direction so as to deflect during insertion into but resist removal from within an interior space defined by the locking recess.
