I need to replace the channel balances in a window 51"x 32". The markings on the channel balance is 29 9 HX CMC. Do you have a channel balance that I could use to replace mine? I have attached photos.

Please see our S385-30 channel balance. I think this could be a good match for you. You will have to weigh your sash in order to confirm the proper stamp option.
