3x3 Wooden Arris Rail (75mm x 75mm) Brown Treated - 3.0m

Arris rail is a triangular length of wood cut designed for use in close board fencing. They are secured to the fence posts most typically by cutting the ends of each length down to fit a socket within the fence post, which creates a sturdy and secure base to hold fence panels or boards. Sometimes they are instead secured with Arris rail brackets. It is treated to UC3 to help protect against moisture and pest damage, and is suitable for outdoor use with no direct contact with the ground.

Arris rail is typically installed horizontally between two fence posts, and secured two the posts by inserting each rail (usually with a tapered end) into a notch or mortice made in the fence post, or by using metal Arris rail fixing brackets that hold the rail and are secured to the fence post. Once the rails are firmly secured with appropriate fixings, the fence panels or boards (typically feather edge boards) are secured to the rail to form the complete fence. 

Our wooden 75mm Arris rail is sold in a 3m length and is cut from pressure treated timber. 

Whilst we endeavour to keep this length available and in stock, there may be occasions where stock is unavailable or limited in your area, in which case we will aim to substitute you a longer length or equivalent treatment wherever possible.
