Electrical boxes are attached to a beam using a single fastener, such as a screw or nail. The boxes may be old for work, new work, dual purpose and for dual purpose vertical or horizontal attachment to a vertical beam. The fastener used is guided through a hole in an interior bracket setting the fastener at an appropriate oblique angle to exit at the beam attachment hole on the exterior side. To prevent rotation while using a single fastener, molded extending tabs are provided on the mounting wall to properly align the box with the beam to which the box is to be attached. The tabs prevent the box from being rotated on the fastener during the fastening process. After box attachment, the tabs are folded over and torn off at their weakened attachments.
