Abstract: A ceiling support system for a suspended ceiling is provided that includes resilient clamps for attachment to the underside surface of a structural ceiling and inter-engaging ceiling runners that are shaped to be fitted into and be grasped by such clamps. The engagement edge of the runner is shaped to allow the runner to maintain multiple stable positions: a normal, ceiling panel supporting orientation, and a canted orientation for installation of ceiling panels. Runners may be joined end to end with an engagement piece. Cross-runners may be joined to runners with an engagement piece interfitted with a connector plate mounted transversely in the web of a runner.
