I was asked to repair a few windows by one of my clients. I have attached a picture of the balance. Any help would be greatly appreciated.

I think we can help, but we will need a bit more information. There should be a shoe or clip at the end of the cord. Can you show us a couple pictures of it? That would be a huge help.
