ABSTRACT:
An improved weatherstrip includes a longitudinally extending backing strip, having a front surface and a rear surface; a sealing body attached to the front surface of the backing strip; and a plurality of longitudinally extending grooves formed in the rear surface of the backing strip for reducing the frictional forces between the backing strip and a mounting slide, increasing the surface area for speeding the cooling of the backing strip during manufacture, and for aligning the strip during slitting.
