The AVF GL202 tilt and Turn TV Wall Mounts allow screens to be tilted and turned to avoid screen glare from windows or other light sources. They can also be used to create improved viewing angles for TVs mounted above eye level or when the viewing angle is not directly in front of the TV. Create extra room space and secure your TV from accidental knocks and tips. The simple three step installation process and patented on the wall levelling function ensure a perfect finish.
