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 grooves which may be used to support the runner in position or define an isolated chamber within the body of the runner. The side walls of the runner have a second groove which is used for positioning ceiling boards on the flanges. Locking means are provided on the end and side of two adjacent ceiling runners to lock the ceiling runners together.
