[Shop-talk] Attaching wiring to steel studs?

[Doug Braun]

Hello,

In my house, a previous owner finished the basement, and the interior walls were done with sheet metal studs (a stupid idea, in my opinion).  On the unfinished side of the walls there is a lot of loose NM wiring for the outlets and light switches which is not properly attached to anything.  So, what is the official, correct way to attach wiring to metal studs?  (Of course, if the studs were wood, I would simply use staples.)  For wire runs that have to pass horizontally, I have already installed plastic grommets in the holes in the studs, but what about the vertical runs?

Thanks,

Doug
