Measuring GOG Joint

  1. Hey I was wondering if anyone knows how to measure the glass on glass joint. I do not mean downstem length, I mean like 14.4, 18.8 etc.
    My downstem is bigger than a 18.8 and its also not 29.9

    I want to say its 34mm because it's a HBG showerhead downstem and I've seen others online at the same diameter.
    Also I'm just straight up curious lol.:smoke:
