Thanks for posting! It definitely sounds like the tension in the balances is too high. However, before we try out any other stamp, we should know for sure what you need. The only way to do that is to weigh your window sash.
Also, what Series balance do you have? I assume it's 31", based on that stamp. Is that correct? If you let me know that information, as well as the sash weight, I should be able to tell you what option you need. |

I've been giving this some thought and I have a few ideas. First, compare the depth of shoe on the new and old balance. Are they the same, or is the new one deeper? If they are the same then check the window track to see if there is a kink on track or even in the sash itself.
Also, if possible, do you have the same size window with undamaged old balances? If so, use those balances in the problem window and see if they work. That will let you know if it's even the balances that are the problem at all. If all else fails, you can consider going down in weight rating and use a lower option. It's not recommended but it may be the last recourse. |

Ah, I see. In that case, I think your only recourse is to drop down to the 3030 option. I can't guarantee it will work, but I honestly can't think of anything else.
