Patent ID: 6957896

Claim:
An aperture edging member for forming a substantially smooth aperture within a surface member, said edging member being formed as a unitary member of complementary shape to surround the entire periphery of an orifice formed in said surface member, the aperture edging member including: a substantially planar rim having inner and outer edges and which is perforated, segmented or castellated, and which is adapted to be attached over a portion of said surface member about said orifice formed in said surface member; a lip extending outwards from said inner edge of said rim to a lip extremity such that, following installation, a layer of settable material is adapted to be applied over said rim from the lip extremity at least to said outer edge of the rim to form a surface finish over said rim which is substantially flush with the remainder of the surface member not covered by said rim, and a flange extending orthogonally from the inner edge of the rim in the opposite direction from said lip so as to fit within said orifice and thereby define an inner surface of said orifice which extends substantially orthogonally to said surface finish.
