Hi there!

With this combination of attachments, you could have either an S380-27 or S385-27 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. If your window sash weighs exactly 18 pounds, you'll need the 2630 stamp option for a sash weighing 13 to 19 pounds. You might want to re-weigh your sash to confirm that it indeed weighs 18 pounds.

If you have any further questions just let us know.
