Hello,

We'd be happy to look into this for you but we would need to see an undamaged balance fully removed from your window, including both end fittings, to compare to our inventory. The numbers stamped on your balances can be used to choose the corresponding strength options once we identify the correct balance series for your windows. Thank you!
