KEAH Roof Batten Joint


The KEAH roof batten joint is the most efficient tool for installing roof battens.

Our Roof Batten Joint reduces batten wastage as it allows unrestricted placement of joints, even in between rafters. Less sawing means less damage to underfelt and no split ends from nailing.

Using a simple push fit technique this product enables you to lath your roof in a quarter of the usual time. We have also designed the Roof Batten Joints to incorporate tile clips where required.

The KEAH Roof Batten Joints are made from lightweight and robust polypropylene. They are exceptionally durable and have been tested and certified to support in excess of 30 stone (199kg) and are the strongest roof batten joints in the world.

Available in 2 sizes to fit standardised battens and sold in packs of 20.
