The design is very well thought out and can be easily put together, albeit with some time effort. The large perforated plate, the movable bracket and a whole bag supplied screws make the bracket actually "universal", even for relatively large projector as my Epson EH-TW3200. Very advantageous: the bracket can be assembled on the ground and bolted to the projector and is then inserted only into a sort rail which is screwed to the ceiling. With the four supplied screws and plugs the mount holds bombproof on the ceiling. When only drawback I have to add my voice to the previous speakers, in white instead of gray, the holder would be perfect.
