C58 6#28 10/80 Andersen Balances

Hello there!

Thanks for reaching out to us. I'm afraid we can't identify which Andersen sash balance you'll need from these numbers. May we see photos of all the other numbers stamped on the balance? 

Thank you for getting back to us. Based on the 6#23 stamp in your photo, I recommend the 24-637 Andersen sash balance. Take a look at the specifications and let us know if you have any questions.
