Window channel balance 22 2 LW CMC 11 and Take Out Clip
Thanks for posting. Many channel balances are 'generic' and used by a ton of different manufacturers, so don't worry about that. That stamp code tells us the balance's strength, but not the identity. If you can show us the nylon attachments at both ends, we should be able to identify what you need. Furthermore, I'd like to see pictures of the 'guts' or underside of the metal channel. Some balances from the west coast have a special configuration we need to account for.
As far as the take-out clips, many channel balances use the 16-002, but there's different kinds, so pictures of an old one just to be safe would be best.
Thanks for getting back to me with these photos. This looks like either the S380-23 or S385-23 Channel Balance. The only difference between these two balances is the depth of the bottom nylon shoe. See below. Measure your old balance's shoe depth to see what matches best. In either case, for a stamp option choose 2220. Let me know if you have further questions!
