Hello,

I can't tell for sure based on your photos but it looks like both the top and bottom balances attachments have wings. If so, 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. 

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.

I'm looking for the series 385 but the stamp options go up to 2670, and I need 2690. Is this available?

2690 is part of an outdated weight system that is no longer used, which is why we recommend weighing the window sash and following our chart to choose the correct strength option.
