Abstract: A device allowing a sole installer to install overlapping board siding on a wall is described. The device includes an s-shaped hanger having a u-shaped portion and an inverted u-shaped portion sharing a common leg. A handle extends horizontally from the lower portion of said hanger, substantially perpendicular to the common leg. To install the siding, the installer hangs the first board run. Next, the inverted u-shaped portion of the s-shaped hanger is placed over a first board of the first board run and a second board to be installed is fitted within the u-shaped portion of the s-shaped hanger. The installer fastens the far end of the second board using a single fastener so that the second board can pivot about the fastener. The installer returns to the first end and pivots the second board to free the hanger. The installer rotates the hanger so that the common leg fits under the first board and the handle extends upwardly parallel to the side of the wall.
