Hi there!
With this combination of attachments, you could have either an S380-24 or S385-24 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 will also need a 2340 stamp option for these balances.
If you have any questions just let us know!
This looks like it may be over 1" but photos can be deceiving so I can't say for sure. If you'd like a peace of mind, you can see our return policy here.
That's great to hear! We truly appreciate your business, and if you have any future hardware questions, you know where to find us!
