Sapphire "hidden treasures" projector mirror.
The product has a motor to control the mirror which retracts into the ceiling when not in use..
So your projector is installed in the ceiling and the mirror then provides the image to your screen. When not in use you can press a button or control automatically to retract and close and you have an almost invisible installation.
Being a Sapphire product you get a 3 year warranty as standard.
It is designed to fit a standard 600 x 600 ceiling tile or of course can be used with traditional plasterboard if cut to fit. You only need 170mm clearance in the ceiling height which makes this product work where many traditional projector lifts cannot be installed.
