Please see our S390-29. This appears to be a good match, based on your helpful measurements.

Ah, I'm glad you weighed your sash. I always feel that it's better to go off of the sash weight than the stamp, if you have the opportunity to check it. I would recommend the 2850 in your case. It's possible the original installers simply didn't have that strength spring on hand when they put in the windows. Did you ever find that the windows were a little harder to open?

Yep, sounds like the original springs weren't nearly strong enough. I'm confident the 2850 will ease the operation of these windows.
I am very happy to help. If you ever need anything else, please let me know. |
