Anderson window balancer

Question

Trying to find the proper replacement for the balancers. The original ones I removed have a couple different identifying numbers sets stamped into them. The first set I found was 11600-17. The second set is BJ16 519 6-88. I know the last 3 digits are a date code. The window was purchased and installed in the fall of 1988. I can not seem to find any info to match to the proper replacement. I seem to get several suggestions but not the exact match. Hope you can help thanks.

Hey there, thanks for writing in. Your Andersen balance appears to be our 24-531. Given the 519 stamp on the metal, I am confident this is the replacement you'll need. These are used for balances stamped with a 519, 523, 525, 527, or 531.

Let me know if you have any questions.
