2x3 stud structural integrity
So i'm looking into mounting my tv over my fire place, I can see the wall cavity b/c i have access to the back of the fireplace which looks like a sheet metal box from the closet. Looking around back there i noticed the studs above the fireplace consist of 2x3's instead of 2x4's. I have a 55" led tv which is pretty light considering the size a mount that weights about 60 lbs. for that amount of weight do you all think that mounting onto 2x3's will be fine?
