Need a window crank that fits a 7/8 shaft with 3 splines
Hello,
We'd be happy to look into this for you, but we'd like to see your operator with the window open so that the arms that move the sash are fully visible, including the end of the arm that attaches to the sash track. That would help us determine if any of our handels would be compatible with your assembly. Thank you!
I also noticed another thread with same window.

Thanks for getting back to us. Your operator resembles the Pella 39-175, which uses the 39-109B handle. I suspect that your spline may have come loose, which is why the handles aren't fitting properly. If so, you'll need to replace the entire operator for the handle to attach properly. We also offer the 39-176 opposite-handed version of this operator if needed.
Great! We'll be here if you need anything else.
That's great news! Just let us know if you have any other hardware questions.
