Abstract
A wall angle for a suspended ceiling, which may either be a drywall suspended ceiling or a lay-in tile suspended ceiling, has a cross-section forming a substantially right angle of the vertical leg and a horizontal leg. The horizontal leg is adapted to support an inverted tee-runner that has a vertical web and opposed flanges, the opposed flanges being adapted to rest on the horizontal leg of the wall angle. The horizontal leg is formed with a plurality of pairs of locating tabs, at least one tab in each pair being upwardly extending and vertically-oriented. The tabs in each pair are spaced apart a distance sufficient to accommodate the width of the opposed flanges of the tee-runner. At least one of the tabs in each pair has a downwardly extending detent adapted to permit installation of a tee-runner, but to inhibit removal of the tee-runner. The pairs of tabs are spaced, on center, a pre-determined distance that depends upon the intended application of the wall angle.
