Hahaha you guys are killing me
It’s called (wall control) it comes in different colors. It’s steel. I chose galvanized because it reflects light and I like the way it looks.
Amazon sells it. It attaches to studs 12” or 16” on center. It has its own hook system and uses pegboard type also. It hold a tremendous amount of weight.
I am thinking that anyone getting through a concrete wall is going to make quick work of the mesh... if it does not come down at the same time as the concrete.
