Channel Balance Replacement

A handy person from Georgia says:
Hello
I need to get the correct part number for my channel balance. The length of the channel is 29", width 1/2". It appears that S380-39 might be correct but the width of the shoe is a little bit shorter than the 1" marked in your photo and I am not sure of the extra code I need. I have included photos and the printed code (28 3 CN CALDWELL).
Thanks

Thanks for posting! I agree, I think our S390-29 is the closest match. The 15-005 shoe is the most shallow option that we have at 1". I think it may still fit in your window, but you might have to shave a bit off for it to be comfortable.
A handy person from Georgia says:
Thanks for the confirmation. Just to be sure, the four digit weight code I need will be 2830?
Thanks

That's what I would recommend, yes, but you might want to weigh your sash and makes sure it matches, just in case.

Just wanted to say Thanks!
The new channel balances arrived today and the replacement was quick (like two minutes)and easy. The window is working better than before - now I know why it was squeaking so badly - the channel balance was failing.
Anyway, thanks!
