ABSTRACT:
A suspension ceiling grid having removable grid members is disclosed. Such grid is of the basketweave type and includes a plurality of grid assemblies interconnected to form a grid. Each assembly is provided with a similar first or male connection at its ends and second or female connections at its center. In the grid, the assemblies are interconnected so that the male connections of adjacent grids meet with and connect with the female connections at the center of the assemblies to provide a basketweave type system. Each grid assembly includes two similar grid members each having a first connection at one end and one-half of a second connection at its other end. In the assembly, a removable clip provides a semipermanent connection between adjacent ends of the two members and the two halves of the second connections cooperate to provide one full second connection. Individual grid members may be removed from an existing grid and replaced without creating the situation in which the grid is unstable.
