Replacement Milgard sash balances

Question

I have a customer with a number of disabled Milgard windows. I removed one sample and the spring loop at one end had failed. The body of the sash balance is 22", however the stamp on the side is "20 C", which I don't see listed anywhere. What would be the equivalent current stamp replacement?

Thanks, Bryan Wilde

Are you measuring just the metal channel, not including the attachments or nylon fittings at either end? If the metal channel measures exactly 21", a stamp code of 20C would conform to our stamp option of 2030. If in doubt, please show us pictures of the balance.
