Arris rails

Arris rails are commonly used in modern fencing to support feather edge boards for strong, angled fence structures. Their triangular cross-section allows water runoff and helps deter climbing. These rails are typically installed horizontally between fence posts or vertically for site hoardings and temporary works. You’ll find them in both domestic and commercial settings, particularly where durability and stability are priorities.

Traditionally used in timber-framed buildings and boundary marking, arris rails remain a standard solution for professional fencing. Products are widely available in treated softwood, usually in standard lengths such as 3m. Options include notched or unnotched variants, depending on your post type and fixing method.
