Did not buy here the holder. I have in the store several brackets (were built there) tried: this should make anyone who so wants to define a product, because many work already overwhelmed with the Plexiglas as a replacement TV. This bracket has decent pivot points, so even my 55 "TV stuck with 18,5kg on the wall. The movement could go a little easier. Growing is carried out thanks to the large holes in the bracket at slightly slipped boreholes horizontally home improvement. The bracket on the TV had with me the problem that was Gebau the power connector in the way. But thanks to the included spacers that was not a problem, only the connector no longer goes now from the TV, or I have to solve 4 screws, so to get over. The hook and the last adjust then goes really fast and easy, despite 18,5kg. Would recommend to anyone.
PS: My bracket I (3cm thick) mounted on a wooden panel. My feeling told me three M10 threaded bolt with nut and washers by screw it to get the necessary support.
