ABSTRACT:
A support for tamper proof securing a light fixture including a housing having a peripheral mounting flange on a ceiling panel including a fixture receiving opening having spaced apart side and end margins surrounding the fixture receiving opening and having inner and outer surfaces. The support has a hanger bracket which bridges the opening at a location between the end margins. Each of a pair of spaced apart jacks adjustably mounted on the hanger bracket has an abutment which is movable into a backstop position relative to the outer surface of the respective fixture receiving opening side margin. A suspension device on the hanger bracket is connectable with the light fixture housing, after the fixture housing has been inserted through the opening, for moving the fixture into a finally installed position wherein the side margins are clamped between the mounting flange of the fixture and the abutments on the jacks. In a preferred embodiment, the abutments are separate hold-down bars which extend along the side margins of the fixture receiving opening.
