Hello,

With this combination of attachments, you could have either the S380-28 or S385-28 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 to locate the stamp on your balance channel to choose the corresponding strength option since either 2730 or 2740 will support a 19-pound sash. Thank you and let us know if you have any other questions or concerns.

Thank you Casey for your help,
Unfortunately there are no stamping or printed numbers on the original balances. I measured as you indicated and the S380-28 is correct. I will go with the larger weight 2740. Again thanks for the help.
