Correct Operator for Andersen?

Hello, Sam. I'm afraid the given information does not tell me what operator would be best for your window. Would it be possible to see a photo of the original? If possible, please show us the whole mechanism without obstruction. Thank you!

Thank you. This is a good photo of the arm, but I also need to see the base. Like I mentioned previously, a picture of the complete mechanism without obstruction would be ideal. That way we can be sure that no important details are missing. There are an absolute ton of potential replacements at this stage so it would be best if we see the whole thing in one shot. That would save you a lot of time in the long run. Thanks!

Thanks! My primary recommendation would be the 39-264. Look it over and see how well it compares.

Dimensions for 39-264

Yes, that does look like a match. Just one last thing to note: if your window was made anywhere from 1995 to 1998, then you'll additionally require the 39-362 adapter plate. There should be a date of manufacture somewhere on the window frame, or even the glass, that tells you when it was made.

Please let me know if you had any other questions!
