Hello, We'd be happy to help you identify your balance, but it can be very difficult to identify a balance that is still installed in the window. Could you confirm whether the top nylon attachment on your balance has the plastic wings that jut out to the sides like the bottom attachment? Sending us another picture of the entire balance removed from the window would also help us confirm this. Thank you! |

Yes, that is S350-26. I'll flag down a more experienced researcher to look into that nylon part, though. I'm not sure what it does. What function does that part serve? |
