Abstract
A system for hanging objects from conventional suspended ceilings comprises resilient clips snap-fitted to ceiling rails, an installation tool for controlling the clips, and an elongated pole that threadably couples to the tool, enabling clip manipulation. Each clip comprises an upper clasp, an integral, lower hook, and a midportion. Clasp jaws that yieldably deflect apart comprise opposed flanges that forcibly grip the ceiling rails. The installation tool comprises receptacles for temporarily receiving the clips, and an internal, threaded bore mated to the installation pole. Each receptacle comprises a pair of generally planar retaining arms that partially block a captivation slot. The midportions of the clips slidably fit within the installation tool captivation slots. When pushed towards the ceiling rails the jaws snap apart and surmount the horizontal rail portion. When released, the jaws retract, with their flanges firmly gripping the rail.
