A first of the four side walls of the box includes a first projection extending substantially transversely of the cavity. A substantially tubular extender having a first side wall including a first flange extending transversely thereon, and a tubular base extending transversely thereof. The first flange and tubular base are spaced from one another and a first fastener extends through the first projection, first flange and tubular base to couple the tubular extender to the electrical box.
