This concrete gravel board for closeboard fencing is often used in conjunction with concrete morticed posts. Installation is easy. You simply fix the gravel board at each end to the fence post with a roofing bolt. You then use a square plate washer to secure the concrete gravel board to the special two pin cleat. You can fix the timber centre stump to the gravel board with one 80mm coach screw. At AVS we would only supply an excellent quality concrete gravel board. Closeboard fencing always looks professional with a gravel board installed.
