Figure No. 2 Old Design
Figure No. 3 New Design
The prior design can be discerned from the new design by comparing the ends of the two weatherstrips. The difference appears where the weatherstrip
grips the metal flange. In this area the new design (see figure 3) has two contact flaps, where as the previous design has only one contact flap, and
saw-tooth-like extensions opposing the flap (see figure 2).
