Roof anchor installation for sloping roofs
Pay attention to situations when battens are thicker than the auxiliary board (30 mm). Then the auxiliary board
shall be mounted on an underlay so that its total thickness equals to that of the battens (see pic.).
When installing anchors on a rafter, use an underlay as well depending on how thick the battens and counter
battens are, so that the installed anchors do not hinder proper seating of tiles.
