Knob and Tube Wiring
This was the type of wiring done from the late 1800's to roughly 1940. It is now obsolete and can be considered a safety/fire hazard.
This is the knob. The wires are fed through the guides to keep them from touching the walls.
These are the tubes. The tubes insulated the wood from the wires.
This is how the tube went through wooden beams and supports. The tubes insulated the wood from the wiring
In the insulation in my attic, there was evidence of the wire covering being chewed on. A fire hazard!
I had all the wiring replaced for peace of mind. It was a big and messy job! Expensive too!
The original light fixtures had to be rewired too! I kept what I could because I loved most of them!
