Hello,

We'd be happy to help but we'll need to see a photo of your operator with the window open so that the arms that move the window sash in and out are visible. Thank you!

Your operator looks like an older version of our 39-329 but I can't tell if your link arm has the same downward effect with the screen in the way. Take a look and see if the 39-329 and 39-330 operators could be the replacements you're looking for.
