Hello,
We'd be happy to look into this for you but we would need to see photos of an intact balance removed from the other side or an identical window to research your replacement options. Please make sure to include an undamaged version of the end fitting shown in your second and third photos. Thank you!




Thanks for getting back to us. Unfortunately, it looks like you may have a type of balance that Marvin has exclusive rights to. You may want to try contacting them directly to confirm if you have one of their windows and if they can supply your replacement balances. I'm sorry that we won't be able to assist with this repair but please let us know if you have any other hardware questions.
