Hello, We'd be happy to look into this for you but we will need to see photos of both of your balance stamps, as well as the top and bottom fittings to compare to our inventory. We'd also like to see the metal clip attached to the pulley cord that is used for installation and we can go from there. Thank you! |

Thanks for getting back to us. I agree that your photos look like a match to the S770-27. I would recommend weighing your window sashes and following the chart under the balance product description to confirm the correct strength option for your replacements. |
