<p>The noticeboard is e.g. for holding a notice composed of a number of separate sheets. It has a covering of transparent panels (4), each of which covers one of the sheets (2) and is retained against the backing board by fixing elements. The fixing elements can be in the form of strips of dovetail-section channelling, and the transparent panels can be made from a synthetic material.</p> |
