Help me replace my window sash balance

Quick Learner from Massachusetts
Hello,

My Andersen window sash balance has these numbers on it: 11600-2 and below it is stamped
B75 4#25 8 82
What part would replace that?

Thanks,

Nate

Hey Nate. See our 24-431. This will replace old Andersen balances with the stamp 425, or 4#25. Let me know if you have further questions.
