Hello there! Thank you for reaching out to us. Based on what I see here, my recommendation would be the S395-37 channel balance. Your 36 9 stamp is outdated and doesn't correspond with any of our strength options. With that said, you'll need to weigh your sash and refer to the chart under the product description on the S395-37 store page to determine the appropriate spring strength option for your balance. |
