Chief's PAC-400 is the ideal accessory for projects that need a large flat panel to easily rotate from landscape to portrait. The PAC-400 easily installs into Chief's patented 14" x 14" Q-Latch Mounting System and offers the smoothest rotation on the market. Adjustable Rotation Friction can easily be set to customer preference. 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 19 lbs. and 1.0625" depth to installation (be sure additional weight does not extend plasma mount weight capacity).
