Chief's MAC-400 is the ideal accessory for projects that need a medium flat panel to easily rotate from landscape to portrait. The MAC-400 easily installs into Chief's patented 8" x 8" Q-Latch™ Mounting System and provides ultra smooth fingertip control. Rotates from landscape to portrait (90 degrees clockwise or counterclockwise) with little effort and no tools necessary and has 2 degrees of over-travel for easy leveling of screen. Cable management holes on front plate prevent binding or damaging of cables. Bracket adds 6 lbs. and adds only .94" depth to installation (be sure additional weight does not extend wall or ceiling mount weight capacity).
