A support for a fixture for a lighting or other electrical device, on an acoustic ceiling, so that it will be supported firmly without wobbling. In the preferred embodiment it is a rectangular metal box with an open bottom, formed from a single sheet of metal. It is dimensioned and configured so that a mounting box for the fixture can fit inside. The mounting box is prevented from moving by the broad, flat top surface of the invention. There are diagonal rows of large holes through the top side for electrical fittings, and smaller circular holes for support and grounding screws. It can be supported on the beams of the ceiling by screws that pass through slots in its ends, by using fire tie tabs, or by a stab connection. The longer side walls have flanges which rest against the top surfaces of supporting cross pieces for ceiling tiles.
