Window Balance Identification Needed

Question

Hello. I am curious about what window balance I need to replace the balance in the photos. The windows in the house are likely over 35 years old and none have the balances installed anymore. Stamped on the side of the balance is "16 2" with a smaller "G 1" next to it. It is almost 17" long, not including the plastic pieces on either end.

Hi there,

Thanks for posting! Your window balances can be replaced with either the S351-17 or the S390-17. You'll need to confirm the depth of your bottom shoe to determine which series is the correct one for your window.

You can likely use the 1620 stamp option but it would be a good idea to double check that you sash weighs between 8 to 12lbs.
