Hello, We can't be sure without seeing the entire balance assembly fully removed from the window but what I can make out resembles the S770-28 (28C), which uses the same terminal clip at the end of the pulley cord. These balances also have a hole at the top of the channel used to attach it to the window jamb with a screw. Review the specifications shown on our product page to confirm if these balances will work for your repair. Thank you! |
