Abstract
A support structure for an electrical box includes an elongated support member which is fastened into a hole in the rear wall of the box, the depth of insertion being determined by a stop flange. The length of the support member can be adjusted to approximately match the distance between the rear wall of the box and the inner surface of a sheet of wall material behind the rear wall by breaking off portions of the support member at one of a plurality of weakened regions formed by a uniform sequence of annular recesses. The support, thus installed, limits motion of the unmounted end of the box.
