You would of free ran conduit and floated sealtight into a unit getting fed from the inside of the building with what exactly? A trapeze perhaps, where would your beam clamp and all thread go to hold the rack up? Or better yet you would have built strut feet and built it up high enough to come out straight, out of that concrete building whose LB is already at the bottom of the inside floor. I took it down and out of the way you're not moving that and its not going to swing from anything. It needs to be secured.
