Abstract
A self locking mounting bar having a notch near one end, which notch fits onto the upper edge of a main runner of a suspended ceiling. The other end of the bar slides into one end of a lighting fixture frame. The bars are generally used in pairs to provide an adjustable mounting apparatus for recessed lighting fixtures; a pair of bars mounted at the same end of the fixture frame, but on opposite sides thereof, may slide toward or away from each other to accomodate variable ceiling runner spacings. Preferably, two pairs of self locking adjustable mounting bars are used to mount a fixture, one pair at each end of the fixture frame. The bar is mounted by placing the notched portion of the bar onto the upper edge of a ceiling runner. The bar then may be locked in place by bending a tab at the end thereof underneath the upper edge of the runner.
