Can you show me the nylon fitting on the other end of the balance as well? From there, we should be able to help. Many thanks. |

Thanks for getting back to us! Bob's not here today but this is a pretty straightforward identification and I'm confident that I can help. Based on your photos, I believe you have our S350-16. This has a 19-002 top fitting and 15-004 bottom fitting. As long as those match up then you should be good to go. |

Sure thing! Since your old stamp reads "15A," I recommend the 1510 option. The logic being A = 10, B = 20, C = 30, and so on. |

I'm very sorry that the product you want is out of stock. Unfortunately, I don't think a stronger spring will work as well. Your window will be more difficult to close due to the extra tension and it could even drift up on its own, if the difference is too much. It's ultimately up to you, but I thought you should know the risks. |
