Abstract
A ceiling runner is disclosed for use in a ceiling grid system of a suspended ceiling. Each of the main and lateral runners of this ceiling grid system has a similar shape in the flange at the lower end of a generally T-shaped structure. Such flange has first and second flange portions on each side of the web portion, and these flange portions are joined to the web portion by first and second connector portions which are recessed toward the web portion. This establishes a longitudinal recess in the exposed surface of the flange so that a distinctive appearance of the ceiling runner is provided which has definite longitudinal delineation between the ceiling panels. Preferably, the connector portions are shaped to maintain a panel in its proper centered position or to cam such panel to such centered position. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
