Replacing the coil balances for a 23 year old bathroom window. The coil is 1/2" wide and is stamped with 64C.
From your coil replacement page it looks like S190. Can you tell me which one I need?

Hello,
Since your 64C doesn't match any of our stamp options, I recommend weighing your window sash and dividing the weight by the number of coils in the window to choose the correct option. If you could show us the pivot shoe that the coils anchor to, that will help us confirm that the S190 is what you need. Thank you!
