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.

Abstract: A surface waterstop is in the form of a strip of rubber or plastics material. At least one keying formation, preferably a T-shaped formation, is provided on each side of a center line of the strip. A longitudinally-extending central section may be provided for receiving and locating stop-end shuttering. Along at least one lateral edge, and preferably along both lateral edges, the strip is adapted, for example by the provision of holes, slots or the like, to receive fixing pins or clips which, in use, extend at an acute angle to the surface on which the waterstop is laid.
