Fence panelling (16) is fixed to and between said posts and extends over the height thereof. An extension (30) may be fixed to the upper terminal end portion (24) of each post to project inwardly and downwardly to the common side to which the posts incline, and panelling (32) is mounted on and extends between the extensions (30). A dual fence installation is also described which precludes scaling from both sides.
