I be use this mount with a optoma hd20 and it have do a great job . it will take you a few minute to sort out what need to be do with the piece in the box , but it be not hard and very flexible ... look like it would fit just about any conceivable projector . the material be pretty high quality . be aware that the minimum height from ceiling to where it grab you projector be about 15 '' -lrb- not 12 '' as some have say -rrb- . I need it to be about 12 '' for my application , which be in-between this mount and most of the other that I find . a friend point out that it be just two aluminum piece that slide and it could easily be cut down with a hack see without any visible change . so I cut about 6 '' off of the end each of the side to get the correct range and drill a new hole for the length set piece -lrb- this be easier than be sound -rrb- . warning : there be a little tab of punch metal who be job be to keep the two arm from completely separate - if you cut these down you 'll lose that piece and risk the possibility that if you loosen the arm length screw the projector will fall . I suggest that if you do this you set the length and then drill a a additional hole to secure it . -lrb- in practice however you would have to really be not pay attention and have a heavy project for this to happen . -rrb- my only other comment on this be really more related to the Optoma hd20 - for some reason optoma choose to place the three mount screw hole off center on the projector bottom ... so when loose the projector want to hang to one side . I can see no logical reason for this ... just dumb . not hard to overcome , but annoy . again , nothing to do with the mount , just the projector .
