Searching for Coil Balance w/ stamp 532

Thanks for posting. That stamp indicates you have a coil spring that supports 5 lbs of sash weight individually. I'm afraid though that this does not tell us what type or Series of coil spring you need. The best way to know this is to see a picture of the pivot shoe that this coil spring attaches to, as the identity of the coil spring tells us the identity of the coil balances needed. From there, we should be able to help you. Many thanks.
