This box is a (Hubbell) Raco 3.5" "Ceiling Box".
They've been around since the days of knob & tube wiring.

Where would you use this particular box??...S

See question #11: https://www.electrical-contractor.net/Education/Mike_Holt_Code_Q&A.htm

Substitute 314.16 for 370-16

Only on a ceiling fixture or wall sconce with a canopy that meets the wire fill requirements.

Well, it's 4.0 cu in-so it's perfect for old fashioned 14-2 Romex with no ground.

I've seen lots of these above sinks in bathrooms on residential work.
Seems that darn plumber always vents straight up, and there's almost always a stud right there...S
TG, yes when they enter from a domed fixture.
Now, what about the ground wire in the 14-2 romex?? It doesn't count?

Not if you cut it off before it enters the box...who needs a ground for a light fixture anyway?

(NOTE: That was supposed to be sarcasam...)

These things always seem to get added onto over time

Now, let's deduct 1 conductor for the clamps

I never use the 3.5" ones and never with clamps.

Ceiling fixture that lands on a joist and sconces that land on a stud.
They are some of the best support for heavier fixtures since the mounting point is centered on the box.

I've used these before, and reasoned that the Fixture Dome effectively adds volume to the box that can be divided up for conductor fill. It has been a solution for some tough situations.

But ... strictly speaking, 370-16(B)(1)Exception seems to say that the 'domed luminaire' or canopy space can only be used to avoid counting the fixture wires.
