Thanks for posting. I don't quite recognize this pivot shoe. The identity of the pivot shoe should tell us the balances you need. Could you remove it for a closer look and tell us its width and thickness? See the videos on this page for assistance.

I believe I can help. These are the following parts I believe you will need for your Simonton window.
- For two fifteen pound sashes, use (4) S160-7 springs, (4) 15-228 Pivot Shoes, (4) 15-150S Spring Covers, and (4) 26-378 pivot bars.
- For the one eighteen pound sash, use (2) S160-9 9 pound springs, (2) 15-228 shoes, (2) 15-150S covers, and (2) 26-378 pivot bars.
- For the twelve pound sash, use (2) S160-5 5 pound springs, (2) 15-228 shoes, (2) 15-150S covers, and (2) 26-378 pivot bars.
As Bob recommended, it's best to remove your old hardware and compare just to confirm these items match up. Let us know if you have further questions.
