What are them cheap looking restraints holding that rubbish to the wall?
Those clip-things (they have a name which eludes me at the moment) are used to hold vertical
runs of EMT to concrete. I see them in parking garages, basements, etc. They hold the EMT off the wall just enough that you don't have to make a 1/2 inch bend to connect it to a box. I have never seen them used for a horizontal run of EMT, though I suppose they could be used that way. This is a commercial ice cream shop near where I live. The line runs to one of the huge compressors for the freezer.
