Sturdy, reliable and strong. Closeboard panels are an excellent fencing product and come in a variety of sizes. Works best with concrete slotted posts and concrete gravel boards. With either a 6inch concrete gravel board or a 12 inch concrete gravel board these panels can be made in 5ft 6inch, 5ft, 4ft 6inch, 4ft, 3ft and 2ft heights. Constructed using feather edge timber onto 75mmx32mm backing rails (not 75mmx22mm like some other panels). If you require 4 backing rails to make even sturdier panels then please get in touch.
