A:AnswerIt should work with most 50 in tvs. Check your back brackets and the weight specs. When hanging be sure to account for the weight of the tv. Otherwise even though technically level it may look crooked when you tilt it because some TVs are heavier on one side. We had to raise one side of the mount 1/4 inch to account for weight for it to look straight to the eye.
A:AnswerThere is a "quick release" cord but that only loosens it to a certain extent. You must then remove one little screw to remove the TV from the wall mount. So it is a quick 2-step process.
A:AnswerI doubt it's a stainless steel product since these are normally indoor only. It does however have a good coating on it. Might be powder coat, might just be paint. Honestly I would worry more about your TV than the mount.
