Thank you for the great website and videos! I bought a house and almost every channel balance is broken. I looked at the common channel balances on your website, but mine appears to be a little different. The windows are from MI Windows and Doors series 865, but MIWD says they do not have the part any more. The channel is 15" long and it says 1440, BSI, and DC or D6 or DG (the text is very small). I can look up the window identification codes if that helps. I attached pics of the top guide and shoe. Thanks for any help!

Hello! I'm confident we can help. This is a special kind of balance that will need to be custom made. Fortunately, your pictures tell us everything we need to know. before we begin, can you just tell me how many you need?

Hi Tom,
Thanks for the help! I have 19 of these windows, and now I see that for 6 of them, the top guide does not have those wings. I removed a pair and it seems like they were made without wings, rather than something that broke off. I'm not sure what that means. Anyway, I guess I would want 18 balances, assuming I can replace the wingless ones with winged ones.

Ah, I see. Well, those guides are an important feature, but there is some wiggle room. They act to align the balance so that it's centered in the window track. It's possible the winged ones can replace the wingless ones, assuming there is space in the track where they install. If not, you could potentially clip the wings off. Or, we can make you an entirely new set of balances with the appropriate attachments. I will email you a custom order link for 18 of the 1440 balances, but if you want to change that let me know!
