Andersen sash support

Question

Hello,

I have a C30 6#30. Which support should I purchase?
Is there a cross reference that I can access?
Thanks, John

Hello! The key stamp here is 6#30, but that's not a number I've ever seen before. Would it be possible to see a picture of it? That may help us determine which Andersen balance would repair your window.
