Abstract
A wall channel for a drywall ceiling has a generally U-shaped cross-section with a vertical leg interconnecting two generally-horizontal legs. The lower 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 lower horizontal leg is formed with a plurality of pairs of locating tabs that are spaced apart a distance sufficient to accommodate the width of the opposed flanges of the tee-runner. The upper horizontal leg is formed with a plurality of pairs of locating tabs that are spaced apart a distance sufficient to accommodate the width of the reinforcing bulb of the tee-runner.
