The Beast XXL - Heavy-Duty XXL Full Motion TV Wall Mount

The Mount-It! Beast XXL Full Motion TV Wall Mount (MI-394XL) is the Beast Series flagship — engineered for the largest flat panel TVs on the market. With a 38.6" maximum extension, 110° total swivel (55° left and right), and support for screens from 75 to 140 inches and up to 275 lbs (4x safety-tested), this is the full-motion mount for living rooms, home theaters, and commercial installations where standard mounts simply aren’t built for the job. A friction hinge mechanism delivers smooth, controlled movement across the full range of motion, while ±5° screen leveling ensures precise alignment. The mount retracts to 4.3 inches from the wall when not in use, and the 27.5" x 11.5" wall plate supports dual stud installation at 16" or 24" on-center spacing.
