This is something we do see every now and then. We don't have an operator in your size, unfortunately, but the 39-089 should still work. I recommend trying it out as-is to see if it opens your window normally. If you run into any issues, then the best solution would be to adjust the position of the bracket on the sash to make up for the difference. I've done this myself in the past and find that it works well. It will require drilling new holes, though. |
