Included in the delivery was Tons of screws, thus the right for any purpose. Plus expansion anchors + 6 hex bolts. So if you want to play it safe, so can every 6 kloppen on the wall. However, I would like to remind you of the support of such power plugs: If I'm not mistaken, so already an anchor holds 100 kg 2 screws should therefore be sufficient.
Although it has been looking forward to for washers enclosed arched backs of televisions were (as many have a subwoofer that's necessary!), But they were of poor quality. 2 are broken because I had it probably meant well with the tightening. A lucky enough were doing. And even if such a time breaks and falls, so the TV can not fall off the wall, get more than a bit skew. So do not worry about the good part!
What annoys me but very is that I can not completely just fix the wall mount, because I simply do not have just a reference point. The integrated water level is a joke, as each Handyapp is more precise. But that was expected. So fix brought the calibrated level of the workshop, created, screwed, TV off, wrong!
Reason is that the folded-over edge was not completely parallel to the rail with me where the 2 holder lie. Thus, it should be observed during installation, that the water level is applied to the top of the holder 2 and not on the track. Thus, one should be spared to manufacturing tolerances.
But because the holder is slender, the manual helpful, the price super (commercially costs such holders more than twice!) And my criticism can be avoided by a little creativity I give the product even 4 stars.
I can recommend buying.
