Feather Edge UC3 Treated Timber Board 150 x 22mm has been cut diagonally meaning that one edge is thinner than the other. This is ideal for using to create fencing, and classing of sheds or buildings. It can be used without needing to change any existing fence posts and creates a neat and decorative fence. Any cut ends need to be treated and sealed with the appropriate wood preservative. It has been UC3 treated meaning that it is suitable for external use, above ground only.
