Thanks for posting. Silverline windows have used our Series 765 Tilt Window Channel Balances in the past, but I can't say with any confidence this is what you need without seeing pictures of your old balance out of the window; specifically, of the attachments at either end of the balance. From there, we can say with more certainty what you need. Many thanks.
