Triple coil window system

Thanks for posting! To recommend the correct coil balance replacement for your windows, I'll need to see a photo of the assembly removed from the window.

I'll especially need to see a photo of the pivot shoe and you'll also need to have it removed to compare measurements. Once we've identified the shoes and the coil springs needed for your window, you'll need to review the coils for any stamps or markings that may be on the coil. This will help to determine the spring strength for your window.
