I have a Peach tree French door that has been troublesome for awhile. Having them out of business has been a pain in the butt. They has some proprietary weatherstripping that is no longer available and the parts are getting harder to find. I had to replace the door lock because my dog was landing on the handle repeatedly and it eventually broke the lock internally. I turned the handle from 3:00 position to 12:00 position so he had no leverage so It should be fine. I bought standard weatherstripping and cut off a sliver and it seals well now….
