coil balance broke

Question

Hi. My window will not stay open and it looks like my coil broke. I think it is an MI Window. Looks like a double coil assembly (based off your site). Are your parts universal in size and what do you think would work to replace my broken part? Thank you!

Your balance shoe resembles our 15-180, while coil springs should be our Series 190 balance. You will need the number from the old springs to order new springs. See what you think.
