Sliding glas door seal

Question

The white, plastic seal screws into the outside door of the slider.  It has a rubber edge which seals agains the glass of the inner door.  It apparently keeps wind from blowing between the door window panes and causing heat loss and water entry.

I'm afraid I can't ID what you have from this photo. Can you take a clearer picture for me? If this is a kind of weatherstripping, we will specifically need you to remove a sample and show us the end profile. The video below will clarify what I mean.
