Arris Rail Green Treated 75x75mm (3m)

Arris Rail Green Treated 75x75mm (3m) is a pressure-treated softwood fencing rail, cut to a triangular profile and sized at 75 x 75mm x 3000mm. Designed for trade and DIY use alike, it is the essential structural component in traditional closeboard and featheredge fencing systems, providing reliable bay support across the full 3-metre span. The green preservative treatment penetrates deep into the timber, delivering long-term resistance to rot, fungal decay, and insect attack in exposed outdoor environments.
