Abstract
Abstract In accordance with a preferred embodiment of this invention, there is provided an elongated elastomeric weatherstrip, having a longitudinally extending sealing portion and a longitudinally extending U-shaped base portion which clamps the weatherstrip onto a projecting edge flange or the like. A reinforcing and retention aiding core is embedded in the base portion. This core comprises a plurality of resilient U-shaped metal strips disposed transversely to the longitudinal axis of the base portion in closely and uniformly spaced relation therealong; the strips are securely attached at their ends to flexible continuous cords longitudinally disposed in each side wall of the U-shaped section. The base portion also has one or more longitudinally extending projections along the inner surface of the sides of the U-shaped channel to more securely clamp the weatherstrip to the edge flange.
