There are the holder at all screws and dowels for mounting in a concrete or brick wall. For other materials it is necessary to arrange the attachment material itself. For me it should be a concrete wall and thus the attachment was nothing in the way. The very large screws need etas force to be driven into the wall. A powerful cordless screwdriver is an advantage here. For my Toshiba 32WL66PS with Vesa 200x200 drilling the plate for holding fitted perfectly. The appropriate screws for this purpose were there.
The scope for give left and right is relatively small during the up and down several times greater and, in my view, also important, is.
So far everything seems very stable and also the operation and installation is / was very simple. I am very pleased at the price of 40.
