Channel Balance

Question

I'm looking to replace a few channel balances for my vinyl windows. They are 27" in length and 1/2" wide. The stamp on the balance says "26 3". The space isn't a typo. I checked a few balances on the windows to make sure the 3rd number didn't get worn off but they all had "25 3". The windows are approximately 15 years old and the only sticker I found on them said "Sponsored by AAMA" so I'm unsure if that is the manufacturer.

With this combination of attachments, you could have either an 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. You'll also need 2630 spring strength options to replace the balances in your photos.
