A flange cover for embracing engagement with and clamping retention on a flange edge. The flange cover is an elongated strip of a generally U-shaped cross section defining a pair of legs connected by a web. Each leg has at least one retention lip extending inwardly therefrom and is made of a lower durometer thermoplastic material than the web. The flange cover is made by extruding a flat, elongated strip with a middle portion of higher durometer than side portions, said side portions having retention lips projecting therefrom, and then bending the strip along its longitudinal axis to form a flange cover having a U-shaped cross section.
