ABSTRACT:
A co-extruded all-polymer weatherstrip has a retainer including a base portion and support portion, an elastic portion extending upwardly from the retainer for providing the desired and needed resiliency, and a generally rigid contact strip supported by and integral with the elastic portion. The rigid contact strip is self-supporting so as to retain its shape and position without becoming creased, wrinkled or bunched-up when subjected to sliding action.
