ABSTRACT:
An electrical outlet box is formed from side plates and an U-shaped plate forming top, bottom and rear walls. The side plate has bosses, projecting outwardly from the box to ensure that the box is uniformly spaced from a vertical surface, for example the side of a stud. To facilitate mounting of the box to a stud, at least one boss has an aperture therein for receiving a screw or other fastener. Preferably, this aperture has an axis angled so that the axis passes through the front opening of a box. The bosses with apertures can include planar central portions for receiving a screw head and further can have an outer portion to the aperture for receiving part of a screw head to minimize protrusion of the screw head into the box. The screw head is then recessed away from the interior of the box to prevent shorting of electrical context, and as it is located in a boss contacting the stud or other surface, unwanted distortion of the side plate is avoided.
