Thanks for posting. Can you confirm the weight of your sash? The original balance stamp (13 4) is for sashes weighting 11 through 12 pounds, and corresponds to our 1340 option. Was this the original balance from the manufacturer? It's very unusual for them to be so far off. Did you ever find this balance to have difficulty keeping the window open?
If you are certain that the sash is 16.6 pounds, we can custom make a balance for you with a special option. Please just tell me how many balances you would need and we can get started! |

Well, my concern with making a stronger spring is that it could be too strong, which means there's a chance it could actually damage your window. The best case scenario would be that you couldn't close your window at all. If you found the 13 4 rating worked fine before, it might be best to stick with that.
