I'm afraid I can't confirm if our hardware will work for you without more information. I don't know what style coil balances you have. The 15-140 is meant to work with the Series 150 spring. Does this match what you have now?
We have detailed pictures and measurements for each part on their respective store pages. I recommend carefully comparing our details to your hardware and window to confirm that they will fit. |
