Overview

The Full Motion TV Wall Mount with Articulating Arm is a full motion (articulating) TV wall mount compatible with 32 to 55-inch televisions and rated to hold up to 77 lb. Designed for rooms where seating spans multiple angles and the screen needs to track the viewer, like living rooms, open-plan spaces, and bedrooms with off-center mounting positions.

Swivels 90° left and right, tilt +10°/−15°, and extends 2.75 to 24.25 in from the wall. The long extension arm pulls the screen far enough from the wall to swing past furniture, fireplace surrounds, or room corners without obstruction.

Compatible with VESA mounting patterns from 75×75 to 400×400 mm. Also supports corner wall installations for rooms where flat wall space is limited.

A practical choice for large living rooms, corner installs, or any setup where the screen needs to pull far from the wall to reach the optimal viewing angle.

Reviews

Customers say this TV mount is sturdy and extends well from the wall, with many praising its 24-inch extension and full 90-degree rotation capability. Users find it easy to install and appreciate that it holds TVs securely without sagging. Many reviews mention the mount works well for corner installations and tight spaces. Common feedback includes concerns about the cable management clips, which customers say are weak and don't hold cables effectively. Some users report quality control issues with mounting holes not aligning properly or wall plates being warped. While most find the swivel mechanism smooth and adjustable, a few note the tilt function can be loose on heavier TVs. Overall, customers consider it good value for the price despite minor hardware limitations.

    ok - but it is flawed

    I purchased this unit but disappointed they do not supply you with a mounting pattern on where to drill the holes. I took the mounting plate off and made my own - I know they push a mounting service but not interested. After I took the plate off is when I found the defect in the quality of the item. The mounting holes for the arms do not line up and needed to be bent in order to align for the arms to fit. Very disappointing - the metal is thick but build quality is poort

    Sturdy design poor execution

    Sturdy enough but the wall plate was not flat and would have rocked on the wall. Fortunately the steel is very soft and I was able to hammer it flat without damaging the powder-coat too much.

    Ok

    After I leveled out the wall mount piece arm piece and tv the tv is not level once extended and turned. This is super distracting and unsightly. It looks like the arm piece attached to the mount is not straight and therefore affects and tilts the tv. Annoying that I paid the amount I did for that kind of quality.

    Well made

    I bought this mount because I needed one with the extension length that has. The shorter ones wouldn't work for me.I think it is a decent mount. It's plenty strong and stable was straight forward to mount to tv and wall. It's also easy to move and adjust the tv position.Two negatives are that the lag screws and washers that are supplied are not black they are bright silver (like most screws and nails) so you will have to replace them or paint them unless you don't mind looking at them. My previous mount had black screws so I used those. Second the clips supplied for cable / wire organizing are beyond useless. They will not work. They can't even hold one cable or wire. You'll have to come up with your own solution.Lastly there are some drywall anchors provided for installing in drywall. IMO that's a bad idea. Install it into a stud.In the end I am happy with this tv mount. I think it's a fair price and it does exactly what I bought it for. I gave it 4 stars because of the useless wire holders (why even include them??) and the lack of black screws. I would recommend this mount with those qualifiers

    High Quality TV Mount

    I am very pleased with this wall mount. It's heavy duty and my 40 TV doesn't sag to one side under the weight like my old wall mount used to. You can adjust it all directions. Like others have noted the only negative is the cable clips that don't hold the weight of the cables very well. Easy fix with zip ties or velcro. Would definitely recommend!
