    摘要： A universal skirt board has a base, a top flange section, an overhang section, and a sealing flange attached to the top flange section. The base has at least one ridge extending away from the base in a first direction, and a projection extending in the first direction. The top flange section is attached to the base. The overhang section is also attached to the base and defines a drip edge. The sealing flange is attached to the top flange section. The at least one ridge is formed to rest on a top of a base board. The projection is formed to fit into a slot defined in the top of the base board to provide an interference connection.
