A ceiling panel (32) that conceals the grid in a suspended ceiling, having opposed active edges (A,B) with kerfs (33,35) of different profiles, for engagement with the grid, and opposed passive edges (C,D). Kerfs of different depths at different levels in the active edges (A,B) permit the panel to be inserted, or removed, by successive hinge actions as shown. When installed, the panel (32) is locked to the ceiling with no visual indication as to how it can be removed. |
