Need help identifying window springs.

No identifiers on window springs or windows. Would like to order replacements for the entire house. Please let me know if I can assist with any additional pictures or measurements.

Thanks for posting. This looks like the 15-180 Pivot Shoe, which works with Series 190 Coil Balance springs sold separately. Let me know if you have further questions about any of this hardware.

Thank you! I don't see any markings on the coil balance. Do you know which stamp I should order?

If there are no stamps on the coil springs, weigh the window sash this setup supports. Give us that exact weight and we can work out what you need. See the video below.
