Abstract: A protective cover to cover an opening of an electrical box having a threaded bore on inwardly projecting protrusions. In one approach the protective cover may have a back panel and four side panels together defining an interior cavity; a flange connected to a free edge of the side panels; wherein the flange has a pair of keyhole shaped bores defining a pair of openings along a center longitudinal axis of the flange; and wherein the keyhole openings are configured to allow a head of a screw to extend from the threaded bore and through a rounded portion of the keyhole opening and to allow a threaded shaft of the screw to slide along the length of an elongated narrow portion of the keyhole opening, the narrow portion being narrower than the diameter of the screw head.
