The VisionMount VM400 is a full-motion wall mount for 26" ? 42" flat-panel TVs up to 100 lbs / 45.45 kg. It can be used alone or with the LR1A recessed in-wall box. Virtual Axis allows smooth, effortless tilt motion with the push of a finger, making it easy to reduce glare and find the perfect TV angle at any height. Full motion allows maximum flexibility - extend, tilt and swivel your TV up to 20" / 50.8 cm from the wall in every direction for easy viewing from any seat in a room. Post-installation level adjustment allows the TV to "roll" up to 6 degrees clockwise and counterclockwise to ensure it is perfectly level.
