Hello, thank you for posting!
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.

Comparison of the S378, S380 and S385 balance shoes.
You will need to measure the length of the channel from metal to metal. You will then need to review the strength chart on the product page to choose the correct weight option. Please let me know if you have any questions.
