Finding premier mounts for flat panel televisions, speakers, or projectors is tough. Sometimes it is worse than doing the actual mounting work itself. I know I hate going to the local big box stores and dealing with employees who are not trained to answer my questions. More than once, I have come home with the wrong item, just to make the return and come home empty-handed. I found the best solution is to go online and find a store specializing in mounts. They will have the knowledge to tell you what you need and you will have the right item the first time around.
