A:AnswerI have a 55" Samsung smart tv; we used this Rocketfish full-motion mount to attach it to the fireplace. Works great. You'll need diamond bits though to anchor it into the brick. Good luck!
A:AnswerWell, it doesn't go forward by any degree since that suggests an angle by which it tilts. If you mean how many inches does it extend than the answer is 5.75 inches.
A:AnswerYeah, you could use it outdoors but I'm not sure it was meant for that. If you do, I'd recommended spraying a rust preventative or covering it.
A:AnswerI've mounted two tvs with Rocket fish mounts. They are very versatile very accommodating to most TV. I would recommend that you mount on the middle of a flat wall. The size and curvature might present some challenges if you were to mount in a corner.
A:AnswerI actually have it flushed again the wall, there is so many options. I am moving next month and I will enjoy the other features it has. So keep all the items you don't use and save it, you may need it or change your mind.
