Need a balance for an atrium window

Question

Hello,
I have a window made by Atrium that slides up and down. It used to have a tether that snapped off and according to Atrium, I need a balance. They told me size is etched on the metal piece which can be seen in attached picture. Atrium told me Swisco will have this part. I am not able to locate this part using your website. Can someone help me with this.

Hello,

We'd be happy to help but we would need to see a photo of an undamaged balance removed from the window, including both top and bottom attachments. The stamp number indicates the strength that the balance spring requires to keep the window raised but, unfortunately, is not a part number used for identification. Thank you!
