The ceiling tile suspension system is composed of a runner structure and a clip structure. The runner structure is generally trapezoidal in cross section with two flanges spaced away from a ceiling structure. The clip structure includes a flat base portion with flanges that grasp the flanges of the runner. The clip structure has a serrated edge connected to the flat base portion and the serrated edge either digs into the edge of the ceiling tile or slips into a kerf in the edge of the ceiling tile to hold the ceiling tile in position against the clip flat base portion.

The invention is directed to a ceiling runner which has a generally U-shaped configuration. The runner has flanges to support ceiling boards. The side walls of the runner are formed with first grooves which may be used to support the runner in position or define an isolation chamber within the body of the runner. The side walls of the runner have second grooves which are used for positioning ceiling boards on the flanges. A closure member is used in combination with this ceiling runner to close off either the bottom of the runner or the top of the runner.
