A cover plate for completing the enclosure of an outlet box, the plate having a mounting screw retaining and aligning assembly integrally formed in an aperture in the plate. This assembly engages and aligns the screw so that the screw will not inadvertently fall out of the plate and the longitudinal axis of the screw is substantially perpendicular to the plate for ease of insertion of the screw into an internally threaded bore coupled to the box. The assembly comprises a pair of opposed, spaced flexible major webs integrally formed with the plate and extending into the aperture; and a pair of opposed, spaced flexible minor webs also integrally formed with the plate and the major webs and extending into the aperture. The major webs have parallel, straight distal edges which form chords of a circular aperture in the plate. The minor webs are in the form of ring segments. The assembly further comprises a countersink formed in the aperture and coaxial with that part of the aperture containing the webs. The outlet box can contain an electrical device such as a switch or receptacle and can be located in a wall. |
