Abstract: A bracket for use with cement board siding may be used to fill in a gap that may have formed over time between the ends of adjacent boards that have been installed on the side of a building structure. In some implementations, the bracket comprises an elongated rectangular plate having a top edge, bottom edge, and rear surface. The rear surface may include a spanning feature that extends outwardly from the rear surface such that when the bracket is installed into a gap between adjacent siding boards, the ends of the spanning feature mechanically contact the ends of those boards. The bottom edge may include a return portion to engage the bottom edges of adjacent siding boards when the bracket has been installed. The top edge may extend upwards beneath one or more siding boards located above the gap in the boards.
