You definitely need a channel balance, but I can't tell what you have. I don't know if the Series 775 is a match or not; I don't see the tell-tale "scoop" shaped shoe in your photo. Is there any way you can remove the balance from the window? If not, we would at least need a clear photo of the top and bottom ends of the balance. If there is a shoe or clip at the end of the clip, we would also need to see that.
