What balancer do I order

Question

I have what appears to be 200 Narroline Anderson windows. I need to replace the balancers. Here's all the stamped numbers on the old parts:

11600-17

831 K46 399

11600A-3

What parts should I order?

Any assistance would be greatly appreciated.

Thank you,

Lee

Hey Lee. See our 24-837. This is meant to replace Andersen balances that include the stamp '831'.
