Have a variety of Alenco window sizes in a home we just moved into.
The main type I am looking for is close to your S390 with 15-001 at bottom and a 19-002 at the top. The difference is that the 19-002 at the top is right in dimension, but mine has wings. All other units with wings you have are odd dimensions. I attach some photos.
I noticed one of the smaller windows had a newer balance stamped caldwell installed. This had the 19-002 style without wings at the top fitting. Is it possible to use this in a window that had winged version before?

Thanks for posting. See the Series 395 Channel Balance. I believe this is what you have. Let me know if you have questions.
