I have a ceiling with joists running one way, and then furring strips running perpendicular under the joists. I have wires running parallel to the furring strips which are mostly stapled halfway up the joist, but at points they pass under the joists, but above where the drywall will eventually be. How do I protect these wires? Obviously metal nailing plates are usually the choice for wires close to the surface of wood... but in this case they are on the surface. I don't think the nailing plates are intended for this purpose and would squeeze the wire too much unless I bent them (creating a gap for the wire). I'd like to figure out the right way to protect the wire in this situation! (By the way, I know the normal alternative is to just drill a hole in the joists to pass through, but I was hoping to avoid this if possible)
