Hi there!
With this combination of attachments, you could have either an S380 or S385 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 2320.
If you have any further questions just let us know.

If you look on the S380-24's product page, you will see a list of numbers to the right of the product image. The stamp on your metal channel says "23 2" which means you would choose the 2320 option.
Let me know if that helps.
