Anderson Window Balance

Question

Hello,

I'm trying to find the correct replacement balance for my windows. They are Anderson windows manufactured in the 70's I believe. The sashes broke on a these and I need to replace. I can barely make out the numbers stamped on the back of the balances looks like L1527/5?9. See closeup image I have uploaded. Any help identifying the correct replacement balance would be appreciated.

Regards,
Bill

Hello, Bill! Looks like the key stamp here is "527." With that in mind, I recommend our 24-531. This Andersen balance is specifically designed to replace models with that code.
