Abstract: The invention relates to a one piece edge protector trim strip for application to a flange such as that which is found around door openings in motor vehicles. The strip is extruded in a continuous length by a dual durometer extrusion process around a semi-rigid stiffening carrier of generally U-shaped construction so as to provide a body of rubber or plastics material which is of generally U-shaped cross section and is provided on the inner face of the two arms with a plurality of resiliently deformable gripper fins extending inwardly of the arms towards the base of the U which act to hold the strip on the flange and prevent ingress of moisture, and there is at least one gripper fin on one arm of the U and at least two gripper fins on the other arm of the U, the said at least two gripper fins being of a softer material than, e.g. a different compound from, said at least one gripper fin.
