Hello.

We need to order replacement window balances for several old Anderson double hung windows. Image attached. The number says B 4 25 7 70.

Which replacement balance do we need?

Thank you!

Hi Karla. See the 24-431. This is meant to replace old Andersen balances that have the stamp code 425. Let me know if you have further questions.

Hello! Based on your old stamp of 823, my top recommendation is the Andersen 24-837 sash balance. This is designed to replace all older balances with that same 823 marking.

Please feel free to reach out if you had any other questions.
