With the ViewSonic PJ-WMK-301 Overhead Wall Mount Kit, you can easily install select ViewSonic projectors (LS810, LS820, LS830, PX800HD, PS750W, PS750HD) just inches away from a wall. This simple and flexible set up will not only help to produce a large image from a short distance, but also keeps the projector up and out of the way for a more subtle presence.
