It's mechanical so all you worry about is if one bolt can hold the thing you are mounting. Now with 4 bolts and a safety wire I can't imagine me worrying.
Just purchased up the LG 55" display (about 65lbs I think) and we want to wall mount it to a brick wall. We got a Sanus LL22 mount and I'm starting to lay out my level lines and such.
My "problem" is that the vertical spacing between the bolt holes will always give me one row of bolts in the mortar if I get the top row into the vertical center of the bricks. I've seen mixed opinions of tapping into the mortar for TV hanging.
The Sanus came with 1/2" lead anchors and I also picked up a box of the 1/4" X 3 1/4" blue tapcons. My plan is to get 4 of the lead anchor bolts across the top centered vertically in brick and then use the tapcons across the bottom (can probably get closer to 8 of them in). Does this plan seem acceptable? I'm also thinking about adding two more tapcons at the top center and running some steel wire through the mount bars on the back of the TV as an extra safety measure. This is my first time (needless to say) trying to wall mount one of these myself
