ABSTRACT:
A device for suspending equipment such as a lighting fixture or public address speaker from a ceiling mounted track (5) used to suspend a movable partition and including an extruded rail (4) defining a channel having a longitudinal slot opening (8) between flanges (9) projecting inwardly from opposite lateral walls(6) of the rail. The device comprises a threaded stem (13) capped by an enlarged head (14) passes through the slot opening (8) and is engaged by a lug (17) which cooperates with the head to forcibly bear against or capture one or more of the flanges. In an alternate embodiment of the invention the axial movement of the lug along the stem and the rotational movement of the head in reference to the slot are accurately limited for ease of alignment. The device can be quickly loosened to allow horizontal adjustment of the suspended structure along the rail.
