Thanks for posting. I'm afraid I can't confirm exactly what you need based on these numbers. You say that it's like the 39-156, though. When you compared our dimensions to yours, how well did they match up? Did they differ in any way? If so, can you tell me exactly how? It may be best if we see a few pictures of your operator removed from the window before we suggest anything.

Perfect, thanks. I agree, our 39-156 looks close. I just recommend carefully comparing our dimensions to yours to ensure that they are the same.

Sure, the main arm length is definitely important. However, so are the other dimensions. We show detailed measurements on the 39-156 store page for you to reference. If they differ in any way, let me know how.
