Channel balance parts

Question

Hi,

I'm trying to find the parts to repair windows in our Florida room. I looked at several channels and can't really find any part numbers other than the numbers in ch4.jpg.

Any help in identifying a part number would help a lot

Thanks,

Doug

Hello,

It looks like you have either our S351-21, with a 15-002 bottom attachment, or S390-21, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. It looks like your stamp says (20 F). If so, you'll also need a 2060 spring strength option for your replacement balances. Thank you!
