Re: I know some one here will steer me in the right direction
there are some red flags, but if it's the only option then do it or get an installer.
the 46" panel is probalby 70-ish pounds. so you need to install on TWO studs. The one i posted you can see hits two studs and has a few inches of adjustability.
the wall isn't going to collapse, nor is it dangerous if you mount properly, it's just this poses some issues they don't tell you about in the showroom or in advertisements. for example, you also need to get power there & route/hide the cables & place the cablebox/dvd player somewhere (you never see that in the ads) ... glen
the tilting one you showed #370013966784 is what i'd try to use (no articulating arm) either way
