I need a replacement dual arm operating hardware for Marvin Entry Guard casement window (operator's right) with # 20544 stamped on short arm. Window measures 18" x 45"

Thanks/Chris

Thanks for posting, Chris. Could you show us a few pictures of the operator in question? I'd like to see it fully removed from the window, if possible. That will let us find the best possible match. Thanks!

Thank you. I recommend looking at our 39-031 and 39-032. I believe these operators match what you have now. Just make sure the dimensions are the same!
