Yes, it's all glued.



Originally I was going to leave it so that I could swivel the right monitor, but the weight of the monitors causes the pipe to pull forward at a slight angle.



If you want swivel, or tilt, this isn't really going to work for you, although it could probably be modified some to work. Technically they rotate, but since they can't be swiveled, they only rotate until they hit each other.



In my case, I've had Ergotron arms for years now, and find that I'm always bumping something and knocking a monitor out of line. I never move them to a different location, or rotate / swivel them at all, so the fixed arms work better for me.
