This Graphite Black Duofuse 1.8M fencing plank uses a tongue and grove system to make instillation quick and easy resulting in a secure garden fence. Duofuse is made from recycled wood fibre and PVC making it a much more weather resistant and durable alternative to wooden fencing. Duofuse is water resistant and will not warp, rot or swell even in the dampest of conditions. Utilise with small U-profiles and fencing posts to complete your Duofuse tongue and grove fence. Also available in Tropical Brown and Stone Grey.
