Abstract: A universally-adaptable mounting plate for mounting an electrically-operated door opener on a door frame. The mounting plate is substantially rectangular, having a plan portion with longitudinally-directed side edges and transversely-directed end edges. A tab is struck from the plan portion at one end of the mounting plate and is positioned substantially perpendicular to the plan portion and substantially equidistant from and substantially parallel with respect to the side edges. The plan portion is provided with both longitudinally-elongated and transversely-elongated apertures for mounting the door opener thereon, and the tab is provided with an aperture for receiving conventional fastening means for affixing the tab to a door frame or door frame jamb.
