Abstract From the Canadian patent

An adapter for use with a support grid for ceiling elements. In particular the adapter mounts on a horizontal bottom portion of an inverted T-shaped support. The adapter has a first flange forming a C-shaped clip. A plurality of such flanges are spaced along the adapter length so they do not interfere with cross support members. Holding flange portions support the ceiling elements. Additionally further flange portions are provided to prevent transverse movement of the adapter relative to the support. The further flange portions are also spaced to prevent interference with cross supports.
