Hi, Ralph.

Thanks so much for your patience during our busy season. With this combination of attachments, you could have either an S380-21 or S385-21 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 2040 spring strength option. 

If you have any questions just let us know!
