Projector lift is installed so that the daily use is the lift’s
“closed” (full up) position, with projector mounting pole
extending through the finish plate to within 6 inches of
the top of the screen so the projector lens is lined up with
the top of the image when the screen is deployed.
Lift operation is only needed for
technician access to the projector.
