Do you think its a bad idea to use a 1900 and extension box for second floor homeruns? The guy I used to work for would often do this in two or three of the switches so he could come out the top of it 6 times instead of 3.

I have never had the need to do something like that but as long as you can maintain the required 1-1/4" for the cables from the face of the studs, the required conductor length in the box and the box fill I see no problem.

My old shop used to used deep 1900's instead for all the HR's, with 3/4" (EMT) to the panel.

a 1900 box is the most common type of electrical box. you can fit 2 switches or outlets in it.

... Edward, a "1900" box gets it's name from a Raco manufactured 4"X4"X 1-1/2" metal box..their item/model # is 190,...hence the term "1900"...

I thought the 1900 was in reference to 19.00 cubic inches, but it's actually more than that.

In other words it is a shallow 4S box.
Right?

The topic is "residential" homeruns: Why would anyone want to use a metal box in residential? It seems like a BIG waste of money to me...
