Quoted from BrewinBombers:My new build had 0 glass issues, so I'm not sure what the variable is that's causing some folks to have such challenges; that said, it's definitely not every game.
I think there's one worker that really likes to tighten those side rail screws down extra good. After loosening the 2 middle screws on both sides, my glass went from nearly impossible to get off, even with suction cups, to just a little tight. It won't slide out on its own, but I can easily get it off and on now.
