Hello, thank you for posting!

With this combination of attachments, you could have either a 22" S380 or S385 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.

Comparison of the S378, S380 and S385 balance shoes.

To choose the correct strength option needed, you will need to obtain the weight of the window sash and compare to the stamp option chart on our website. Please let me know if you have any questions.
