Hello all, We are currently looking to hang a projector in a School "Cafetorium" (AKA Gym converted to Cafeteria.) Our only mounting options are the steel beams on the ceiling. Does anyone have any suggestions on vendors or suppliers of enclosures or brackets to hang a project like this? Also, what are the best options of providing a source to a projector of that height? We have some wireless projectors, but they are not performing very well wirelessly. Thank you in advance.
