Good Morning;
Is item 39-031 a standard size for all casement windows?
Thanks
Ray
Hello,
Unfortunately, there is no such thing as a standard-size operator that would work for all casement windows. You would need to confirm that the specifications below match up to your original assembly. If not, we would need to see detailed photos of your operator with the window open so that the arms that move the sash are fully visible to compare to our inventory. Thank you!
