22 inch window channel balance

Question

Hello,

I'm looking to replace 3 pairs of channel balances on my aluminum windows. I attached 3 images. They are 22" long and 1/2" wide. The number on the Channel balance is 2140, and is located in the attached images as well. Could you please help me identify which parts these would correlate with your products?

Thank you for your time.

Hello,

With this combination of winged attachments, you could have either an S380-22 or S385-22 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 2140 spring strength options for your replacement balances.

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