Hi there!
With this combination of attachments, you could have either an S380-29 or S385-29 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom attachment, and the Series 385 has a 1-3/32" attachment. You'll also need a spring strength option of 2830.
If you have any further questions just let us know.

The stamp on your metal channel is "28 3" which represents the weight your sash holds. So, you'll need to choose the 2830 option.
