Need ID on replacement window balances

Hello, thank you for posting,

Your balance resembles the Series 395 channel balance. Please review the overall style to confirm a good fit! See the S395-18. The metal channel should have a number stamped that indicates the strength of the spring needed, but if there are no markings, weigh the window sash and compare to the strength chart on the product page to choose the correct stamp option.

Please review and let us know if you have any additional questions!
