I'm confident we can replace this for you, though it will need to be custom made. I'm thinking a channel balance with our 19-041 top and 15-005 bottom. Does that look about right? I just need you to clear up a couple more details.
First, what is the length of just the metal channel? 32-1/4" is a little weird for this kind of balance. Just make sure to ignore both nylon attachments in your measurement, you only want the metal part. Can you also tell me the stamp printed on the channel? That will let us determine the proper spring strength. If there is no stamp, we will need he weight of the sash. Finally, how many did you need? |

Thanks for getting back to us! Yes, if there is no marking on the balance channel then the only other way to determine spring strength is knowing the weight of the sash. Replacing the top and bottom nylon pieces is totally doable, if those are the only things that are damaged, but I'm afraid it's not possible to replace the string and pulley system. If those are broken, you need an all new balance.

Correct: weighing the balance does not help.
