Andersen sash balance

A home owner from Longmeadow Mass. says:
I have 11600-17 stamp also and I found 623 1 1094 on one of the tabs. Is this enough to determine correct replacement balance?

Thanks. Your YouTube is terrific

Thank you! I'm glad our videos have been a help. As for the balance, I recommend our 24-637. This can replace Andersen balance boxes stamped with 623.
