Wall mounting a TV can be a real bitch of a job, particularly if your support beams are all in the wrong position. The Atdec Telehook takes away the difficulty, allowing you to hang any TV under 50kg with a standard VESA mounting hole configuration 400mm wide.
For $149, you get all the necessary mounting hardware, which makes the job possible for one person. The design is only 15.4mm thick, making the wall mounting nice and close to the wall.
And if you're worried about cable clutter, there's also a cable management solution that discreetly mounts on your wall and offers adjustable shelving for your AV gear.
