ABSTRACT:
A trim piece including a generally horizontal capping flange insertable into a gap between a wallboard partition and a ceiling panel, a generally horizontal trim flange having a painted lower surface which extends away from the partition along the ceiling panel and a stem which extends downward over the front surface of the partition. The trim flange extends outwardly at an obtuse angle from the stem at approximately 180.degree. from the capping flange. When the capping flange is inserted into the gap between the wallboard partition and the ceiling flange, the capping flange is driven against the top surface of the wallboard partition, and the outer end of the trim piece is driven upward against the bottom surface of the ceiling panel to cover the gap from view. The junction of the upper layer of the capping flange and the trim flange is at least as strong as the trim flange itself so that any tendency of the junction to bend or buckle will be minimized. Another aspect of the invention is the use of a removable protective strip to cover the painted lower surface of the trim flange during installation. Another aspect of the invention is a method of covering a gap between a substantially vertical wallboard partition and a substantially horizontal ceiling panel with a trim piece.
