Hi there!

With this combination of attachments, you could have either an S380-27 or S385-27 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 2640.

If you have any further questions just let us know!

While I was waiting for your response,I ended up ordering S395-27. It looks similar to the S385-27, what is the difference? Thanks for your responses

The S395 has a top fitting with wings and a bottom fitting without wings, while the S385 has wings on the top and bottom fittings. These wings are very important since they help stabilize your balance inside the track, so I'm afraid the S395 will not work for you. You can see our return policy here. 

Thank you!
