My broken constant force balance springs are stamped "F". They are 1/2 wide with just a single mounting hole on the end. What spring would I need?

Hi there, thanks for posting. We're happy to help find the correct balances for your window, but we'll need a little more information still. If you can send us some photos of the balance removed from the window, we should be able to take it from there. We will need to see the full channel, and the top and bottom attachments. Thanks!

Hello,
Attached please find the photo of the broken spring by itself.
I am away from the house now and cannot send you pictures of the other components.
Hopefully, this is sufficient for you to tell me what replacement springs I would need.
This one is stamped "F"

Thank you.

Thank you for sending this photo to confirm your 1/2" coil spring. You will need the S152-7 coil. The letter "F" represents the #7. It's just a new system.
