Abstract: A wall molding has two grooves formed on opposite sides for receiving wall panels or interchangeable molding attachments. The body of the molding has a rear surface with grooves that engage a track attached to the wall. The molding also has a front surface with a decorative pattern formed thereon. Wall panels may be inserted into the grooves, thereby providing a smooth transition from wall panel surface to the other. In addition, an attachment may be inserted into one of the grooves and a wall panel in the other to provide an elegant transition between two wall surfaces that have different thicknesses.

Abstract: A molding profile assembly has a first and second molding profile. The first molding profile, whose upper surface is to form the upper surface of the molding profile assembly, has a groove formed into an under-surface of a first arm and a groove formed into a foot perpendicular to the arm. The second molding profile has first and second tabs which fit snugly into the first and second grooves of the first molding profile, respectively, interlocking the first and second molding profiles together. The molding profiles do not require scraping, stripping or other permanent alteration in order to be assembled together.
