Hi I have a 42" Panny plasma (TH42PX70) and have just bought the Premier Mounts AM3 (http://www.avrabbit.com/product-Premier-am3-bk-plasma-wall-mount-584.html). The mount weighs 25kg and is good for 41" - 61" screens, so can take the plasma. My worry is the wall and making sure the thing doesn't drop off! What is the best and most secure way? there are some bolts that come with the mount, but there are extra holes to add more bolts. The wall is under currently construction. It is a bare breezeblock wall at the mo, but is having battons fixed and plasterboard over. I have heard of coach bolts that go through a breeze block then 'open out' to stop them slipping out (similar to stud wall rawl plugs?). Other advice has been to have extra battons on the wall so that the screws go through the plasterboard, then battons, then into the wall. Given the weight, any advice or links to great bolts would be much appreciated.
