Hello! With this combination of attachments, you could have either an S380-29 or S385-29 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. A "28B" stamp usually corresponds to our 2820 stamp option but you can always weigh your sash on a scale to be certain. Comparison of the S380 and S385 balance shoes.
