I installed a 40" Samsung on this mount. The adapter plate fitted perfectly. I needed a little more extension, so I bought longer screws (slightly hard to find) and put a 2 x 4 between the mount and the wall.Given that this mount was far cheaper even than other mounts in the Circuit City going-out-of-business sale, I don't see why anyone with a TV 40" or under would by anything else. Make sure you check the specs online, because a few brands of TV need an adapter that is not sold with the unit.It extends, retracts, tilts, and you can tighten various allen wrench screws to make it stiffer or looser.This product works.
