ABSTRACT:
A ceiling panel that conceals the grid in a suspended ceiling, having opposed active first and second edges with profiles different from one another, and opposed passive edges. An access kerf, and a registration kerf, at different levels in the active edges, along with a registration step in one active edge, permit the panel to be inserted, or removed, by successive hinge actions. When installed, the panel is locked to the ceiling with no visual indications on how the panel can be removed. During installation the panel is self-centering and self-aligning.
