We take care of hundreds of homes with older Pella doors that don't have serial Or model #'s on them anymore .This is a door bottom to one of those doors ( in the last 2 pictures) The first 2 pictures are of a door seal. I can't seem to find these & Pella isn't much help .

Start by looking at our 58-181. Look over the dimensions and see if you could replace your old push-in seal with this. Let me know what you think.
