ABSTRACT:
A woodpile connector has a tubular body defined by an open-end lower portion and an open-end upper portion. The upper portion and the lower portion are fixedly connected, at their free ends, to a separating plate, which is secured between an inner surface and an outer surface of the tubular body. The open ends of the connector body have beveled edges to facilitate compression of the wood being forced into the connector body. By aligning the connector portions in relation to the pile sections, while forcing the connector portions into the ends of the adjoining pile sections, alignment of the pile sections is achieved even when the pile sections do not have evenly cut connecting surfaces.
