If you have popcorn ceiling and it so happens that the I-Beam traverses right above the PJ mounting position this in conjuction with a Chief Universal Projector Mount, NOT included, is your answer.
The CMS006W ie 6" white extension screws into any available Chief Universal PJ mount, for that low profile clean looking install, carries cables and blends with popcorn ceiling. Look at the picture, this is how your install may look. Projector is NOT included.
Was on my own ceiling before i restructured my home theater and had to move to a joist mount.
It is in great shape, low price and PayPal and shipping are included.
