ABSTRACT:
The invention is directed to a transition element for use between an upper ceiling level and a lower ceiling level to form a two-level or multi-level ceiling. The transition element has a configured surface, particularly a curved surface. The transition element is mounted with the top of the curved surface located adjacent the plane of the upper ceiling level and the bottom of the curved surface being located in the plane of the lower ceiling level so that the curved surface forms a transition surface between the two ceiling levels. The transition element is held in position by the ceiling runners used to hold the ceiling boards in position.
