Marvin Casement Operator

Question

I need to replace my casement operator on my Marvin window. I installed the window almost 30 years ago and I believe the operator is stripped. It works one way but just unscrews the other. Let me know if part #39-031 will work.
Thanks,
Sean

Hi, Sean.

Depending on the length of your link arm, it looks like you have either the 39-031 or 39-155. Review the dimensions for each to see which matches best.
