What does RKO mean on a drawing?

"KO" could mean "knock-out"; not sure about "R".
Is part in question sheet metal?

The call-out is not standard.
"Round Knock-Out" would be my best guess.
What if any drawing standard, or country, or industry...?

R = radius, perhaps?

Well, OP speaks English and measures material in Inches.KENAT said:
I suggest buying copy of Y14.38 - 2007 Abbreviations and Acronyms for Use on Drawings and Related Documents. If "RKO" is not there, then it is not standard in America.
Or we could start flame war about "industry standards"

Relativistic Klystron Oscillator would be my second guess.
Back in the day it was common to see engineer's initials on drawing notes. Never understood it.

CheckerHater, that was a bit unnecessary.
Back in England I spoke English and used inches about 1/2 the time. There were plenty of non standard terms and abbreviations there V here in the US.
Many component drawings done in other parts of the world that have to interface with components designed in imperial units/American customary will use inches.
Old drawings from many parts of the Commonwealth will be in inches.
Many industry sectors have their own common terms & abbreviations.
Giving/confirming any of this information might help lead to an answer.
dsjon10 sounds like you may need to go back to the drawing originator/whoever you got it from if possible.

Kenat,
Sorry; didn't mean to get offensive.
Would you agree that if it's not in ASME or ISO "abbreviations", then it should be explained on the face of the drawing?

Sure, that's why I asked about what standards/country.
However, from the point of view of answering the OP's question and helping him out is why I asked about industry etc. While abbreviations not in a referenced standard (could be an industry or company standard) or defined on the drawing shouldn't really be used, in practice they sometimes are used - especially where they are common in a specific industry sector etc.
However, I'm guessing you knew that already.;-)

You'd almost think it would be next to the Turbo Encacbulator.
