Fastening a Ceiling Trim

Abstract

A ceiling trim can be used as a track for wiring is formed of two extruded components where the first defines an angle member for engaging the ceiling and the wall and the second defines a front face portion forming a required shape of the crown molding and having a side edges thereof arranged to be located at or closely adjacent the ceiling and the wall. The components are fastened together by strip members on the second which engage behind clip portions. A third component which carries a track to receive clips bridges the corner of the first component and fastens across flanges. This can be removed and replaced by spaced clips. The spacing of the two components can be adjusted to change a spacing of the side edges from the wall to allow illumination to escape.
