This little guy has my Ace window pro stumped

Hi there and thank you for reaching out to us. We've seen this corner with weep holes a few times before but we were never able to track down a match for it, unfortunately. I'm sorry to say that your best bet may be to make new screens with a different corner and make your own weep hole in the corner. I know this isn't ideal though. I truly apologize for the inconvenience.
