<p>The wooden post is for railway or fencing support which consists of planks or partitions, nailed or screwed into stepped ridges or grooves in the post. Posts (7) of required length support a number of planks (9) to form areas (11) used e.g. for plant fences or sandpits. Further partitions or planks (12) serve to interconnect and support the box like structure. The posts have spaced parallel grooves and/ or ridges.</p> |
