Gasket for Simonton Window Bottom

I'm afraid I don't recognize what you have from this photo. In order to ID a match, I need you to remove an undamaged sample and show me a clear photo of the end profile. Dimensions would also be a big help.

The video below will clarify what we need. I wanted to also reiterate that the sample you show us has to be whole and undamaged. If any parts of it have crumbled or snapped off, we won't be able to help.
