Thanks for posting, Roy. Sounds like the balances need to replaced if the strings are broken. You may not need to know the window series to identify what balance you need. Check out our Sash Support Balances & Hardware Section to find what a balance that matches what you have. Once you identify the Series, I can tell you how you can properly replace it.

Thanks for getting back to us, Roy. If you have the S390-29, then you might want to check out our 2860 option. That's usually what corresponds to a stamp of 28 6. You should weigh your window sash just in case, to make sure it's correct.
As for how to reinstall them, check out the video below. |

No, if the window is lighter than the option you've selected, then the window will not operate correctly and may even cause damage to the window. These are very delicate systems and you want to make sure to replace them with just what is needed. I would definitely weigh your sash and make sure that you know the weight.
