unlike other reviewer I put this together without the suspension bar and mount my projector only a few inch from the ceiling . that work fine . actually , my unit do not seem to have enough screw to use the bar . it be very sturdy and be work great . I do not look up in the instruction on the web -lrb- maybe I should have -rrb- but find it quite easy to figure out . the part supply be different from the include part summary though , at least in the number and type of screw include . Mine come with 3 different type of screw for the projector but not enough of the short hex screw , although I make it work just fine with what it have .
