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 channel is 27" and based on your stamp number, option 2650 will be needed. |
