I have used many magic arms in the past and getting a chance to review this was a real treat. Most of my magic arms can hold a monitor but are usually not very sturdy feeling this one is different. From the first moment I positioned it to hold a monitor I was like this feels different from my older ones. Very strong and firm joints. It’s rock solid for go pros also. I have not had the need to use the fence aspect but if it’s anything like the build quality of the arm it’s probably amazing . I have worked with chain link fence and it’s flexible but for a static mount it should be ok unless there is strong wind. For monitors or go pros this is stellar I hope they make other sizes of arms because these are very good.
