The 1900 was in a 3/4" home run I was trying to trace to split a kitchen circuit. I knew there had to be one in there somewhere... hey how about up in the ceiling? Wound up cuttin throught the drywall, paneling, and the stud blocked directly underneath the box to get access.
The photo of the switch and outlets is from the same room. Notice the "compliant" nails and the lack of a plaster ring!
The Front hall switches were mounted in a plaster / lathe wall, with no boxes whatsoever - met with good old knob & tube, with switched neutrals. Luckily, the owner said "fix it so it's right", not "why do I have to?"

He bought the house less than two years ago, and denies doing any "updates". The "hidden" 1900's are a recurring theme - there was one in the partition wall in the basement bath, and another hidden behind screwed-in-place ceiling paneling.
Have found several additional "hole in the wall" installed switches throughout the house. Will be spending next couple of days pulling the K&T, and replacing w/NM, to provide separate home runs as well as correcting the switched neutrals throughout the upstairs. Thank goodness for balloon construction!
It looks like when they updated to 100A service (sometime early 70's by my guess), they "updated" everything in the basement, up to the point where it went into the walls to go up. There, they just terminated the EMT or Romex into 1900's, connected the K&T to the other side, and covered it up. Yeesh.

A "1900 box" is a standard 4x4 surface mount square box. One of those regional slang things, I guess. Not sure where the name comes from, though. Perhaps some manufacturer's catalog number at one time?

thanks bill great stuff. when i first moved to virginia in the late 80's and asked the supply house for a case of 4 squares he said he'd never heard of them and soon discovered i was asking for "1900 boxes" i then had afew more thrown at me like 11b = an 4 11/16 box and 8o= octogon box.
