Hello!

With this combination of attachments, you could have either an S380-13 or S385-13 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 will also need a 1240 stamp option.

Let me know if you have any questions!
