A small downer but not on this list, the plugs were only scrap, they crumbled at the mere view into several parts because they were the cheapest, made of brittle plastic scrap dowels.
As a good handyman but I have always anchors FISCHER in the house and the problem was solved. Annoyed it took me but still, I had no anchor, would I drive 40 km in the next hardware store and have easy route.
The 50 inch plasma depends now stable and secure on the wall, all in all a good holder for little money, were it not for the scrap dowel ...... ;-)
until recently ....
