Hello,

Each of our channel balance series has a unique combination of end fittings, as well as the clip at the end of the pulley cord used for installation. We'd be happy to help you narrow down your options but we would need to see detailed photos of your balance removed from the window to get started. See the videos related on this page to help you through the process. Thank you!
