Hi there!

With this combination of fittings, you could have either an S380-30 or S385-30 channel balance. You’ll need to measure as shown below. The Series 380 has a 1" bottom fitting, and the Series 385 has a 1-3/32" fitting. You'll also need a spring strength option of 2940.

If you have any further questions just let us know!
