Devices in the form of flush-mounting plates are disclosed which are adapted to connect, for example, one or more receptacles to an electrical box that is disposed inside of a wall. Such flush-mounting plates include a back side that is adapted to be connected to the electrical box through a set of screws disposed through corresponding apertures located in the flush-mounting plate and electrical box, and a front side that is adapted to be connected to the one or more receptacles and a cover plate having a planar exterior surface. The one or more receptacles are positioned between the flush- mounting plate and the cover plate, such that the cover plate, one or more receptacles, and flush-mounting plate are connected to the electrical box in a manner that the exterior surface of the cover plate is substantially flush with an outer wall that surrounds the electrical box. In addition, the cover plate may be connected to the flush-mounting plate through a set of magnets or mechanical means.
