Arris Rail Green Treated 75x75mm (3.6m)

Arris Rail Green Treated 75x75mm (3.6m) by Nar Timber Group is a pressure-treated softwood fencing rail engineered for closeboard and featheredge fence construction. Cut diagonally from a 75×75mm square section to produce a robust triangular profile, it slots neatly into V-notched fence posts and provides the structural backbone for featheredge board fencing. Suitable for both trade contractors and DIY builders, this green treated arris rail delivers reliable, long-term performance in exposed outdoor conditions across the UK.

• Treatment: Green pressure treatment to UC3 / UC3.2 — protects against rot, fungal decay, and insect attack for above-ground outdoor use
