Block and tackle balance id

A quick learner from South Carolina says:
Hello, I'm trying to ID a balance spring that is 27" in length with a stamp of 26-5 and a sash weight of 20#. Channel dimensions are 1/2" wide x 1/2" deep. Spring shoe is 1 3/16" wide and 1 7/8" long.

Also can you also provide guidance for sash removal and installation? I am unsure of window make but tilting sash in till perpidicular to frame and lifting or pulling on either side is ineffective. From what I have been able to determine it is a Norandex Extreme or Viewpoint or Prism

Thanks in advance for your assistance, David

Hey, David. We're always happy to help, of course. Your balance appears to match our Series 795 channel balance. Let me know what you think.

As for removal and replacement, it's pretty straight forward. I recommend watching the video below. Now, this video features a different balance from our Series 795 but the principle is more or less the same.
