Thank you for posting! I agree, it sounds like the balance you ordered was far too strong for your window. When measuring the length of your original balance, did you make sure to only measure the metal channel? Also, was the stamp option the same?
The 2640 option can carry a window sash weight range of 19 through 26 pounds. Does your sash's weight fall within that range? Please keep in mind that the weight range information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate. |

I think the best thing to do now is weigh your window sash. Let's see if the 2640 is, indeed, the appropriate stamp. If not, then knowing your weight will help us find out what is. It may also help if we know the height of your glass, so as to determine if your channel length is also accurate.

Thank you. We've been looking over the details of your window sash and balance, and we can't seem to think of anything that could be wrong. From everything we see, you have the correct hardware. We aren't sure why your balances aren't working. Could it be that the top sash guides are damaged?

Aha, I think that was the problem, then. You were definitely using the wrong hole. You may want to look at our tutorial video on how to replace a channel balance to see the proper way to install your own.

Take a look at our 18-171 Alpine Stepped Sash Guide. Could that work for you?
