Hi
How to measure non tilt windows tube balance installed (not removed) As I don't know the length of the tube without removing it from the window.

Thanks for posting. The only reliable way to get the length of a non-tilt window spiral balance is to remove it from the window. The guide below may help you in doing this. See the video below as well that details all the information we'll need about the balance to find a replacement. We'll do our best to help from there.
