Hello! We should definitely be able to help. Can you just confirm the diameter of the balance's outer tube? I think it might be 9/16", but I'd like you to double check for me. If it is 9/16" then you can use our S600-28 to replace your old spiral balance. The charging tool would be our 75-006. Please let me know if you needed anything else. We're happy to help with anything you may need for your window. |
