The mount features include +/-20 degree tilt, 45 degree pan, 90 degree swivel and +/-15 degree roll. How can I determine if this mount will fit my projector? Projectors may have 3 or 4 threaded holes for ceiling mount. First make sure that the projector does not exceed the 22lb weight limit. Next, find out the maximal diagonal of the holes. It should not be over 16". In other words, if the maxim distance of any 2 holes (especially diagonally) is not more than 16", then the mount should fit fine.
