Compatible Screens and Weight

This articulating mount supports flat-panel TVs from 26 to 55 inches and up to 135lbs. VESA hole patterns between 100x100mm and 400x400mm are covered, including rectangular patterns within the 100-400mm range. The steel construction handles the rated load at full extension.

Wall and Clearance Check

Verify the wall can accept lag bolts or suitable anchors for a 135lb dynamic load. Measure at least 16 inches of clear space in front of the wall for full extension. The folded depth is 4.3 inches, so allow that much behind the screen when pushed back. Confirm no baseboard, skirting or power outlet blocks the wall plate.

Upgrade from Fixed or Tilt-Only Brackets

Replaces stationary or tilt-only mounts when side-to-side swivel, 10-degree rotation or 16-inch extension are needed. The jump is worth it for corner seating, glare reduction or accessing rear ports. Not for screens above 55 inches, sets heavier than 135lbs, or pre-2013 models 42 inches and larger that fall outside the VESA range.

Questions about this item

What comes in the box and do I need to buy any extra mounting hardware?

The mount includes the wall plate, articulating arms, mounting screws and spacers for the listed VESA patterns up to 400x400mm. You only need your own drill and appropriate anchors for the wall type.

How do I decide which VESA pattern to use for my screen?

Measure the horizontal and vertical hole spacing on the back of your TV; the bracket accepts any pattern between 100mm and 400mm both ways, covering 100x100 through 400x400mm.

What does the 135lb weight rating mean when the arm is fully extended?

The 135lb / 61kg capacity applies at any extension up to 16 inches, provided the wall plate is secured to studs or solid masonry with suitable fixings.
