I bought a new home where the TV was mounted directly above the fireplace. The gap between the TV and fireplace was a scant 3 inches. I've since raised the TV to the specs provided by the fireplace manufacturer.
I'm mounting a non-combustible mantel above the fireplace to shield the TV even more.
It's 6" high, will protrude 9" from the wall, and is 72" long. It weighs 43 pounds.
The kicker is there aren't any studs above the fireplace where the mantel needs to go. The only two studs available are 68" apart, 6" from each side of the fireplace. The mantel came with three tiny lag screws. They're only 1/8" diameter.
Since I can only use two bolts, I was thinking 1/4" or even 5/16" diameter lag bolts, screwed in 2.5" into each stud?
Will this work?
