Replacement Channel balance

I'm sorry, I'm afraid I don't understand your measurement. Can you confirm?

Thank you. We may be able to help. Can you also tell me what is printed on your channel? If you don't see anything, I will need to know the weight of the sash, instead.

Thanks again. That stamp is a little short, I'm not sure if we will be able to glean anything from it. Would you be able to give me the exact weight of the sash?

Thanks again for your patience. I'm afraid after extensive research we are not able to provide a version of this balance in that length. Are you sure you have the Series 745? The manufacturer simply doesn't make it in that size. If you aren't sure, you can show us a picture of it and we can work from there.

Aha. You do not have the Series 745 balance, I'm afraid. That explains why we've been having such a hard time finding a replacement; we were looking in all the wrong places. Your metal channel is ribbed, which does not match how the Series 745 is designed.

There should have been something attached to the end of the cord, like a metal clip or a shoe. Would we be able to see that? You can see our selection of ribbed balances here to see what we carry as standard balances to get an idea of what we have, but there's a good chance yours will be different.

You have a very peculiar setup, then. Were you able to show us the hook at the end of the cord? Can you also show us the stamp? I know you told us the stamp already, but sometimes seeing how its printed is as much of a help as the numbers themselves.

I'm afraid not. Like Tom mentioned, the manufacturer does not make that size. Other than that, due to the difference in the shape of the metal channel, there's also a chance that the Series 745 won't even fit in the track. I'm sorry we cannot be of more help. I'm confident that with more specific information we can make a replacement for you, but without knowing exactly what you have I am not sure what to recommend. Window balances are delicate systems and there isn't a lot of wiggle room in terms of what can be used as a replacement.
