Would like to confirm the right window balance

Question

I am replacing both balances in my bathroom window. they both have the same identifiers on them. I believe I need 24-637 but it didn't say it was a double sash, which my window is, so I wanted to check. you have to zoom in on the picture to see the numbers but it does read C39 6#23 12-86

Thanks for posting. See our 24-637. This is meant to replace Andersen balances that include the stamp code 623, or 6#23.
