Abstract: The invention relates to the provision of apertures in building board materials, such as in ceiling or walls. A first aspect relates to an aperture edging member for forming a substantially smooth or “flush” aperture within a surface member. The edging member includes a substantially planar rim portion adapted to be attached to the surface member, a lip provided along one edge of the rim, and a flange depending from the lip in a substantially transverse direction to the rim so as to fit within the aperture. The second aspect relates to an aperture edging device which has an intermediate section with a pair of arms depending transversely therefrom to form a substantially c-shaped configuration to envelope the edge portion of the surface member. An advantage is that a strong rigid vertical face is created in the plaster board, minimizing the possibility of damage thereto. Light fittings, or other fittings may be associated with the device.

Abstract: A framing device or support member (1) for framing a fitting, such as a power point or switch (8), within orifice (4) provided in a surface member (3). The device/member is provided with a lip (5) on the extremity thereof which enables a layer of settable material (6) to be applied thereto. A cover plate (9), provided on said fitting (8), is neatly shaped to fit within the framing device/member (1). A substantially smooth and flush surface is formed between the settable material (6) outside the framing device (1) and the cover plate (9).
