Abstract
The apparatus is a transition member to cover the gap between ceilings at different levels which are also offset horizontally. A vertical section is supported at the edge of the lower ceiling and an attached angular section rises from the lower edge at a slope to reach and contact the upper ceiling. The general shape approximates a trough with one vertical and one sloped side. The lower edge of the vertical section and the upper edge of the angular section can include flanges and attached coupling channels which interlock with drywall adapters to facilitate attachment to drywall ceilings.
