Installing electrical fittings outside of the wall
In modular office furniture, I have seen a way to apply the electrical fixtures outside of the wall. The walls were never cut into, but instead a band about 3" wide and 3/4" thick was applied on the wall wherever it was needed, i.e. top, middle, bottom, etc. The "band" was usually made of metal and contained 110v, network cables and, I am guessing, now would be able to contain usb voltage and also audio cables. I am interested in this because it reduces the flat spots you create in a wall when you cut into a wall to insert outlets, etc. When you cut into the wall, you have to remove some of the insulation. Has anyone seen this?
