Extended-Travel Channel Balance Quote

thanks for reaching out to us. We can supply this balance, but it will have to be a special order due to its configuration. Before we go any further, can you verify the length of the metal channel? We can only supply this type with a 25-7/8" metal channel. If your metal channel differs, then our product won't work in your window.

You also mentioned a holder, but I don't know what that might be. Can you show me a photo of the part in question?
