currently have coil balance shoe with a coil balance spring stamped 932 on it- looks like a 190 coil but I didn't see any coil balance spring in your catalog with that stamping? What could I use as replacement or do you have exact replacement??

We don't have a Series 190 coil spring with that stamp, but perhaps we can work around it. Can you tell me how heavy your sash is?
