The fencing panel, made from horizontal rails (3) between vertical posts (2), has the rails and posts connected by dovetail tongued and grooved joints (4, 5) to prevent the rails from separating from the posts e.g. in the event of warping. The rails can be fitted edge-to-edge on top of one another, e.g. with tongued and grooves edges (6, 7), or with gaps between, and the posts are made in two halves (2A, 2B) each with half a dovetail groove. |
