Use your studfinder to find the studs if there is any. In my case, the wall was one inch thick and the other side was the shower. I found the studs first. Then I designed a piece of decorative one inch thick plywood to fit so it hit the studs with multiple screws. The swing arm was then mounted onto the plywood, I used bolts and the nuts on the inside were countersunk into the plywood. Once I mounted the swing arm onto the plywood, the plywood was then screwed into the studs in the wall. I took the swing arm apart and mounted one side to the tv. All I had to do in the end was hold up the tv and put the pin through the hinge in the swing arm. Also, when I mounted the plywood to the wall, I put a cloth strap behind it long enough to wrap around the tv when the swing arm is back. Velcro hooks at each end of the cloth strap hold the tv firmly in place.
