Hi, I'm looking for a window channel balance(s) for an Atrium Window. I had the balance out months ago and took the two photos that I attached. The numbers and letters on the balance are (28 3 FX CMC 4) that you can see in the photo. I am hoping you can identify this balance by this part number, so I don't have to remove the window again. I guess that if I replace the right side balance that I should also replace the left side, which I am thinking are both the same part. My house was built in 2004 and I believe the windows are original.
the metal piece is 29" long and approx 5/8" widePlease let me know if you need more information. Thank you, Tom Sicora
