Who said anything about cutting corners. Putting a cover on this box and calling it done is not a problem nor should it be to a rationaly thinking person. This is NOT cutting corners. My point is that listing violation is thrown around as if there was a body count multiplying every second. I am sure there is not. There are probably an unlimited number of things that can be done that violate certain "listngs" that have no bearing on the use or safety of those products whatsoever. To me it is more code mumbo jumbo to for cya purposes likely championed by the manufacturers.
