Two Gang Box Loose

This is the view inside of the ceiling with the new wire pulled in through the hole in the laminated beam.

The new two gang plastic old work electrical box is ready to be mounted in the wall

The fishtapes have been pushed in and are ready for the wire to be attached and pulled in.
This hole was made using "The Grabowski Method" of cutting holes in drywall. You simply hold your compass saw at a forty five degree angle when cutting to give you a beveled edge. This makes it much easier to patch the hole using the same piece of cut out drywall and some joint compound.
