The XJ-450 is an invertible projector, so the mount is on the bottom of the projector and the projector gets inverted on the ceiling. The XJ-350 is a non-invertible projector, but does have negative keystone correction, so the mount is more like a wrap around shelf. They both are mounted on 1 1/2" NPT pipes from the ceiling.
