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 S380 and S385 balance shoes.
Please confirm that the length of your metal channel is 27" and the option needed with be 2640. Let me know if you have any questions! |
