Abstract: An elongated horizontal transitional trim product includes an elongated, molded, horizontally-positionable stiffening block. The block has a flat, vertical back surface; a flat, horizontal top surface; a flat, horizontal bottom surface; and a front surface. The front surface extends between an outer edge proximate to the top surface and an outer edge proximate to the bottom surface, and has a cross-sectional profile that includes a plurality of interconnected curved and vertical and horizontal flat surfaces. The stiffening block is capable of being secured directly to a flat, vertical surface of a building. The trim product further includes an elongated deformable metallic sheet terminating in respective upper and lower end sections located above and below a central section. The central section of the metallic sheet includes a plurality of interconnected, continuous surfaces in its cross-sectional profile which mate and snugly fit with the cross-sectional profile of the stiffening block.

Abstract: An architectural trim product formed of a metal sheet material that is bent to a selected profile shape by the interaction of mating contoured die surfaces. The product has a first end that engages first edge of a mounting member and a second end that engages the opposite edge of the mounting member. The second end of the trim product includes a bent edge that grips the mounting member to securely hold thereto. The fasteners used to affix the mounting member to the building structure are subsequently covered so that no trim product fasteners remain visible.
