channel balance marked 26 9 fv cmc 2

Thanks for posting. I'm certain we can help you replace this balance, but we need more information to be able to help. Can you show us pictures of the nylon attachments at either end of the balance? Those attachments are critical to determining the balance Series you require. Next, your stamp code '26 9' is from an older rating system we don't use. We will need the exact weight of your window sash. That exact weight will determine what stamp option you need to select for your new balances. Many thanks.
