Comparable replacement for Andersen 7073B

Thanks for posting. I'm afraid t his operator is no longer made, and we won't be able to provide an exact match. That said, consider our 39-365 and 39-366 operators, along with a 39-114L handle. Could you adapt these to work in your window? This is the only possible system we've been able to come up with as a substitute, though we cannot guarantee it will work. These operators utilize the 39-504 track.
