Blomberg channel balance non-tilt window 1/2" wide

A home owner from Napa CA says:
Swisco,I'm looking to replace a failed Blomberg channel balance on a non-tilt window. It's 1/2 inch wide, but I can't pick it out from the photos your website provides.
Length: Metal 22"; overall 23"
Blomberg stamp "2140"
Need two per Blomberg recommendation (recommends replacing both right and left when one fails.
Thanks!

Looks like you have either an S351-22 or S390-22. The only difference between these two balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement, so compare both with your old hardware to see what matches best. For a new stamp option choose 2140.

Bob,you're a hero. I would never have figured it out. (S390-22, by the way).
Thanks,
Dave
