Hello,

With this combination of attachments, you could have either an S380-21 or S385-21 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 weigh your sash to determine which option you'll need. There is a chart on the product page that explains how to choose your option based on the sash weight.

Thank you and let us know if you have any other questions or concerns.

Thanks so much! I measured and I think it's the 1 3/32" - it was hard to tell though as it could go either way. Maybe I need a better ruler. Lol. The sash weighed 26.4 pounds. I ordered (2) S385-21 2050 and I hope they will work. Thanks again for your help!

Great, it sounds like you purchased the correct replacement. You could try measuring another balance in the house if you want to double-check and as long as the depth is more than 1", you're good to go. Thank you.
