NOTE ** NOTE ** Bevel siding is installed horizontally, providing shadow lines which vary with the siding thickness selected. It is available in clear and knotty grades. WRCLA members also produce finger-joined bevel siding in clear and knotty grades, in lengths up to 16 feet. The precision-fitted joins are virtually invisible and stronger than the surrounding fiber.
