Abstract: A wall support for a ceiling support grid with grid members is disclosed. Each grid member can have a top with a bulb, a web extending downward from the bulb, and a bottom with a flange extending from the web opposite the bulb. Examples of the wall support may include a bracket having a C-shaped channel with a back, a lower flange at a lower end of the back, and an upper flange at an upper end of the back. In addition, the bracket may include only one tab in the lower flange for each grid member. The only one tab may be configured to engage and retain the flange of a respective grid member. The grid member may rest on the lower flange. The lower flange may have no other features for positive engagement with and retention of the flange of the respective grid member.
