Balance springs

Hello,

Your channel balance resembles the S395-22, which should have a 22" metal channel not including the end fittings. Your stamp code would correspond to 2140 strength options for these balances which will support a sash between 15-23 lbs. Take a look and thanks for posting!

Great, then you should be good to go! Just let us know if you need anything else.
