Abstract
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.
