Anderson window balances, P61 12#26 11

A home owner from Walworth, NY says:
Hello, I am trying to find a replacement part for both left and right sides of my window balances. The current balances are both stamped the same: 11600-17 (on one side)
P61 12#26 11 (on the other side)
Do you have a compatible part?

Thank you.

Sorry for the delay. We just added a new Andersen balance to our catalog that is the replacement balance you are looking for. See the balance part 24-1231. Let me know if you have any questions.
