<p>The main fence post (1) has a mortice near its top and bottom to take two fence supports (2) that pass through the post, leaving both bolt holes exposed. The fence section between posts is made of two traverses (3) and two vertical risers (4). Bolts (6) hold the fence section traverses together, while other bolts (5) hold the fence section to the fence supports (2). All joints are capable of rotation to suit variations in ground level.</p> |
