I replaced a ( $100) older wall mount for a 32″ and needed something really sturdy for my 40″ Sony Bravia. I ordered this because it said it can mount up to a 5o” and I don’t want to buy another mount if I get a larger TV.This unit is a dual arm and weighs 52# (solid on the wall) I can swivel it to view out the patio door while sitting on the deck so it gets a lot of adjusting. It came with several different size screws and spacers so it was out of the box and up on the wall in no time.I look forward to this mount being around for many future TV’s
