I am looking at mounting a 55" flat panel TV (which weighs approx. 70lbs) on what I believe is a non-load bearing wall, with TV and mount device this could end up in the 100lb range. The wall is in a high (16ft as it has an open balcony overlook) it is in a condoand it runs about 15 ft with a full side then 10 to 12 more feet with just a runner at the top which is about a foot long. Where I want to put it is over a flush mount fire place, (gas fire place). If this will hold the load I plan to use 1x6 or even 2x4 backing as the studs are aluminum. Is this possible?
Thanks!
