<p>Trim for the front frame of a fireplace unit comprises an element (11) of generally channel-shaped cross-section having a web (13), a single return flange (14) extending from one edge of the web for engaging a first edge of a frame member (10), a double return flange (15) extending from the other edge of the web, which double return flange receives a second edge of the frame member opposite the first edge, and a spring biassing element (16) which is sandwiched between the double return flange and the second edge of the frame member to urge the same apart and hence to urge the single return flange of the element into engagement with the first edge of the frame member, thereby holding the trim satisfactorily in position.</p> |
