| These are cheap. I install them anywhere a wire goes through a stud.
Basically a wire is a "trapped prisoner" in this location. The back of the hole will hold the wire while someone drives a nail through it. If you hit a wire in-between studs, the wire can move out of the way or move back.
I install these not only for when the drywall goes up, but also for after that when someone may be driving a nail to hang a picture or whatever.
In a garage I like all wires (in the wall) to be in conduit for when someone comes along and drives all those long nails to hang brooms, rakes, tools, etc. |
