An electrical cover plate includes a base having a planar member. A first set of removable tabs is connected to the base so that removal of the first set of removable tabs forms a first set aperture, and a second set of removable tabs is connected to the base so that removal of the second set of removable tabs forms a second set aperture. The first set aperture and the second set aperture may each be bounded by an aperture periphery line so that the aperture periphery lines intersect. Also, the first tab set and the second tab set may have at least one tab in common, and each tab set may be bounded by a tab set periphery line so that the tab set periphery lines intersect. The tabs may be connected to the base by grooved connectors, connecting tabs, or other connections that removably connect the tabs to the base. The apertures may be shaped and positioned to receive a variety of specified electrical devices, such as round electrical sockets, duplex outlet sockets, ground-fault circuit interrupt sockets, or light switches.
