  • Patent number: 4408432
    Abstract: A trim strip assembly attached to a substrate body including an elongated rigid member fastened to the substrate body and having a terminal end with upturned spaced tabs. A trim strip is secured to the rigid member and has two parallel longitudinal downwardly curved elongated areas and a terminal end. An end cap is attached to the rigid member and trim strip and has a forward terminal end, a top wall, and a rear wall the bottom edge of which abuts the end of the rigid member. The end cap has two spaced flat resilient legs projecting from the rear wall and their forward ends extending beyond the forward terminal end and each leg is in contact with a respective longitudinal downwardly curved elongated area of the trim strip. The legs are spaced from the top wall of the end cap to allow insertion under the terminal end of the trim strip and each leg lies in a plane that bisects the other and at the same acute angle relative to the horizontal plane.
