Hung window

Thanks for reaching out! There is a good chance that we can supply you with a replacement for your coil balance assembly, however, I'll need to see a photo of the hardware, removed from the window. I am unable to identify what you need based on the patent number alone. There are several different parts that come up. So I'll need the photos to narrow them down.

I'll need to see the pivot shoe as well as any other compatible parts. You'll also need to have the shoe removed to confirm the measurements.
