I needed a ceiling mount for my VVME Projector and figured I didn't need to spend money on a professional mount. I wanted something that would be quick and easy and that could swing down low enough to make the image not trapezoidal. This projector does have a keystone feature but it never totally squared the image. And there were focusing issues as well, so a straight-on image was really needed.
This also hinges up when not in use.
Thanks for watching.
