I have attached the bracket to a 10 cm thick concrete wall and it hangs a 47 "LG television large, weighing about 20 kg without stand.
I have attached the bracket with screws 8x8er because I'm a little scaredy cat when it comes to expensive TV that could fall on an even more expensive room wall and thus can equally kill the cat.
However, the wall bracket has a safe and especially strong impression from the outset. At first I am bit timid been with the inclination but even the doubts are gone now.
Accessories were a lot of screws and the manufacturer recommends all to look three months that the bolts are still tight.
Super Price / Super product
(BYOB until the TV is of course on the ground;))
PS:
the water level was totally wrong on both wall mount, but I'll use my own anyway always level. I would give more than 5 star (if it would go), for the special price - / performance ratio, is similar to the but again.
Maybe you should just leave the water level in the production, lowers costs and reduces error sources, but also we need all sooner or later an on-site water balance. :)
