Electure:
You're bring back more now vivid memories.....

The petrified SO/SJ twirled around the jack chain, from the 3"round box, down to the 2-lamp40 industrial. 30 years, in place, serving the <100 watt load, exposed for all to see.

Or, how about the plastic item that provided 3 places to plug-in a 2 wire lamp cord, that was "wired' onto the baseboards? Heck, they even made them that you could 'feed thru' & go all the way around the room. That fine 18/2 zip cord, extending the sole 'receptacle' in the room to two or three other places. On a good day, you could feel the heat.

Of course, the zip cord was protected by the 30 amp edison fuse.
