The Sanus VLF525 is a premium full-motion TV mount for TVs 51 inches to 70 inches and up to 250 pounds. It tilts, swivels, extends and levels with one hand, with separate roll, tilt and swivel controls. Cables stay concealed and assembly is tool-free.
The TV can slide from side-to-side for perfect positioning on the wall, and the safety tabs sound an audible click when the display is safely attached.
The VLF525 can be mounted on a wall or in a corner with a drill, a socket wrench and screwdrivers. It features universal (300 by 200 through 700 by 400) mounting. It retails for $350.
