The Timber Tanalised Cant Rail (75 x 50 x 3600mm) is a specialized, triangular-profile timber rail designed primarily for the construction of traditional feather edge (closeboard) fencing. Measuring 75mm in width, 50mm in depth (at its thickest point), and an extended 3.6 meters in length, this rail features a distinctive angled or sloped top edge.
 
Manufactured from high-grade structural softwood, this cant rail undergoes a professional high-pressure tanalisation process. This treatment forces green wood preservatives deep into the timber core, providing exceptional protection against rot, fungal decay, and insect attack, even when exposed to regular outdoor moisture.
 
In a feather edge fencing system, the cant rail is fixed horizontally between your timber support posts. Its angled top surface is a crucial design feature: it allows rainwater to run off smoothly rather than pooling on top of the timber, significantly preventing moisture retention and extending the lifespan of the entire fence line. The cant rail acts as the primary backing rail to which individual vertical feather edge boards are nailed.
 
Whether you are building a new closeboard fence from scratch or repairing an existing boundary run, this trade-quality tanalised cant rail delivers reliable structural support, smart water-shedding performance, and long-lasting outdoor durability.
