Jamb, Astragal, and Weatherstripping for Pella Door

Thank you for reaching out to us. I believe we can help with the weatherstripping you need, but we'll need clearer photos of the jamb and astragral. There's no way to identify them while they're still installed, unfortunately. Please remove a small sample of each one and show us a clear shot of their end profile. Seeing their shapes will allow us to find the best possible match in each case.

As for the bottom sweep in your second photo, can you tell me the distance between the two kerfs? The easiest way to measure is from the center of each slot.
