The Mount-It! Beast Full Motion Weatherproof TV Wall Mount (MI-400) is the Beast Series solution for outdoor and large-screen installations where weather resistance is non-negotiable. Built from cold-rolled steel with an outdoor powder coat finish and corrosion-resistant stainless steel and copper hardware, this mount is engineered to withstand moisture, UV exposure, and temperature extremes — making it the right choice for covered patios, outdoor entertainment areas, and any environment where a standard indoor mount would degrade. With a 38.6″ maximum extension, 110° total swivel (55° left and right), and +5°/-10° tilt, it delivers full-motion flexibility for 60–110″ flat panel TVs up to 275 lbs. Horizontal slide technology allows precise left-right positioning after installation, and ±5° screen leveling ensures perfect alignment. The 27.2″ x 11.5″ wall plate supports dual stud installation at 16″ or 24″ on-center spacing.
