Arch, you must be getting really good at dealing with frustrations! In my old age I may be getting better. After my garage through-wall ac backed up, drenched the wall and ruined several cases of ammo, I got it out and measured the max opening at 14.5” tall and 24.5” wide. I finally found a replacement at Lowest that they said was 14”by 24”. After making my own sheet metal sleeve to help any water leave by way of the exterior, I wrestled the unit up and tried to insert it. No Go! It measured 14.875” tall. It only took me 10 minutes to cool off and start demolition. It now works even better than the one that was there when we bought eight years ago (that had rusted through the bottom).I can’t wait to hear unFuggly run!
Cheers
