I am looking for a replacement Channel Balance
- Part Number: 26 3 GW CMC 11
- Top: 19-005
- Bottom: 15-005 (1")
- Length: 27"

The one thing I can not figure out is the Sash weight range. Any ideas?

Sounds like you have an S380-27. Typically, a stamp of 26 3 corresponds to our 2630 option, but you should weigh the sash just to be sure.
