I have an old ceiling fixture box, the kind with the stud/hickey in the center that looks like this:
I want to add a fixture to this box (currently it's unused.) I also want to use a SmartHome Insteon relay to control the fixture:
Unfortunately, the relay is too big to fit in the box due to the stud and a large amount of ancient wiring crowding it.
I would like to figure out how to extend this box in a way that is aesthetically pleasing so I can use the relay. I am aware of box extenders like this:
but that would not look great since the extender will be visible between the ceiling and the fixture.
Replacing the box is not an option since it's embedded in a concrete ceiling.
