The electrical box includes a continuous peripheral wall having an open front side, an open rear side, and a channel therein. The front side includes a front facing surface for receiving a first electrical device in the channel. The rear side includes a rear facing surface for receiving a second electrical device in the channel. The peripheral wall has a length slightly less than the width of the structural wall thereby positioning the installed electrical devices flush or slightly less than flush with the outer surfaces of the structural wall. A fastening arrangement is included on the electrical box for securing the electrical box to the structural wall.
