this be a very good projector mount . I have a very difficult install ahead of I -lrb- low basement ceiling , with a support beam block my projector view on the ceiling -lrb- I have to mount the project behind the beam to get my 106 '' image -rrb- . needless to say , this be not go to be a easy install to get the image line up without the beam interfere -lrb- and I have a dlp projector with not many placement option and limited zoom -rrb- . long story short , this mount work . I would have like the three twist screw that connect the projector to the mount to be more flexible without have the projector come loose -lrb- which it do a few time -rrb- . make the ever so fine adjustment be a bit difficult since I could not get a screwdriver in there be only a few inch below the ceiling . I eventually use a drill bit and vice grip to do the job . again , this be about a difficult install as you could probably do and this mount do the job . in most people 's install , you can adjust the arm alone and achieve great result ... I have to use everything I could do to get this to seat perfectly . I highly recommend the mount and I would be surprise if this could not meet you installation need . fit and finish be excellent and the mount will not budge once properly tighten -lrb- which be good because I do not look forward to adjust my projector anytime soon -rrb- .
