simple enough mount to figure out but be warn , no instruction . there be no bolt , all screw just thread the hole in the aluminum and the allenhead be a bit oversized for the wrench . this result in easily strip out either the hole or the screw head . I need to use a hacksaw to cut down 6 '' on both piece to make it flush to we drop ceiling . it be up and hold the projector in place so as long as you go easy on tighten thing down it should do the trick but you may want to spend a few buck more and look for something a bit more `` solid '' .
