39-092 length is too short

Thanks for reaching out! I'm sorry to hear your purchase did not work out for you. I'm happy to take a look to see if we might be able to provide a better solution.

May I please see a photo of your existing casement operator? I'll need to see a photo of the entire operator; the body of the operator as well as the arms and how they connect to the window.

Let me know if you have any questions.
