Hi:
Having completed the wiring in my shop earlier, I found a very useful way to use up some excess wiring materials. These wire organizers are designed to keep vertical multiple house wiring bundles in the center of a 2x4.
I find that you can string about 20 #12 or more stranded wires horizontally without having to tie them up. This will make addition or modifications to the under layout a whole lot easier. Instead of nailing (Keeps excessive jarring from ruining trackwork) I drill 2 holes in each on the drill press and attach with sheet metal screws.
I have not seen anyone else doing this, but just thought you might like to see the application. An excellent way of using up extra's. I bought the original batch at an electrical supply house but bought another bag (reasonably priced) at Lowes.
Thanks... Tom
