I'm wiring a walkout basement which has ~4' high block wall with 2x6
stud wall on top of that. There is a 2x4 stud wall (4' high) in front of
the block with a 1" space between the block and stud wall. I'd like to
run the wiring in that 1" space between the walls rather than through
the studs. I need some THINGY to support the wires. I didn't find
anything at the local bigbox. Nor he

The closest thing I see on that page is the MultiCable Staple. Something
like that would work if it were designed to be mounted on the side of
the stud and extend into the 1" space.

Any ideas on what you would call such a THINGY and were I might find it?
