Abstract: For use in a decorative molding system comprising thin flexible plastic molding strips having clips thereon and flexible tracks engaged by the clips, a plastic corner member provided between the adjacent plastic molding strips and forming a corner for receiving a pair of the plastic molding strips having free ends with their longitudinal axis forming an angle at a corner of a room. The plastic corner member comprises a one piece plastic body having side walls intersecting at substantially the same angle as the angle formed by the edges of said ends of adjacent plastic molding strips. Each wall has substantially the same undulating cross sectional configuration as the adjacent plastic molding strips. Each wall has an upper free edge, a lower free edge and a vertical free edge, an outer surface and an inner surface. A flexible plastic clip is attached to each the wall. Each clip has first end and a second free end.

Abstract: A decorative molding system removably installed at a ceiling and a vertical wall. The molding system includes a thin molding strip of flexible plastic and a plurality of flexible plastic clips attached at spaced points along the back surface points of the molding strip. A wall track of flexible plastic is mounted adjacent the upper edge of the track on one of the ceiling and said vertical wall. Interengagement is provided on the free end of the clip and the track such that when the thin molding strip with the flexible plastic clips attached thereto is mounted on the track by relative movement, the free end of the clip is moved into the gap and the forward leading edge of the track is engaged. At the juncture of adjacent molding strips, one of the molding strips is provided with a complementary shaped plastic segment spaced from the internal surface of the molding strip to provide a cavity.
