Our new Strong™ SM-F and SM-T mounts are solid. Pick one up, and you will easily feel the beefy 3mm thick steel (that's basically 11 gauge) used to make them. You will also notice the post installation leveling screws, built-on lockable tabs and easy to use wall plate to help make your job of hanging those bigger flat-panels that much easier. Underneath its beautiful black powder coat, the SM-F-XL mount is 3mm of solid steel. With TV's losing weight and getting slim, it was time to trim some fat off our mounts. Our wall-hugging SM-F-XL mounts are only 1-1/4" deep for a low profile feel. Leveling a mount is fairly straightforward and rather simple - except when you face a unlevel mantle or just slightly sloped ceiling. We understand the pain of having to re-level an installed mount, so our SM-F mounts include post-install leveling screws for last minute adjustments. Most installer worries we surveyed are in regards to kids knocking the TV off the mount, while some are protecting the TV from being stolen. Our new Strong™ fixed and tilt mounts now include LokTight™ rotating lockable tabs directly on the arms themselves. The lockable tabs keep the arms against the mount, eliminate easy lifting from curious kids, and allows for a locking device to be added for security measures.
