Abstract: A spacer device for use in mounting an awning bracket to the side of a building having horizontally disposed and overlapping siding members. The spacer includes an upstanding rectangular plate having an upper end, a lower end, a first side edge, a second side edge, an inner side and an outer side. An upper screw opening is formed in the rectangular plate below the upper end thereof. A lower screw opening is formed in the rectangular plate above the lower end thereof. An upper hollow cylindrical shim extends from the inner side of the rectangular plate so that the interior thereof registers with the upper screw opening in the rectangular plate. A lower hollow cylindrical shim extends from the inner side of the rectangular plate so that the interior thereof registers with the lower screw opening in the rectangular plate.
