Is the Andersen Vent hinge pair 39-539 difficult to install?

It is a little tricky. You might want to get a contractor to install it if you aren't confident, but make sure he is familiar with your type of window. I'm not sure if the aluminum arms are riveted on your window or held in with a type of "e" ring.
