152110 Anderson window operator

Hello! We actually carry quite a few operators with this same style base. I'm confident that one of them is what you want, but I need to see the entire mechanism in order to narrow it down. Would that be possible?

That appears to be the same photo you submitted originally. Like I mentioned above, I need to see the entire mechanism, not just the base.

Thank you, that's a huge help. It looks like your operator is missing the guide at the end, so I'm not 100% sure, but start by looking at our 39-099 for Andersen brand awning windows. This is designed to replace operators made from 1999 to the present day.

If your window was made from 1995 to 1998, however, then you will need the 39-343 instead. The date of manufacture should be etched on the glass.

Yes, for some reason Andersen likes to change the hole pattern on this kind of operator once every couple decades. I'm not sure why they do it, and there are certainly other varieties out there, but in our experience the adapter plate will allow you to use our hardware for an Andersen window made in the date range I stipulated before.
