That's not true about bipass doors only being hung in sheetrock openings. I've only hung them a few times in sheetrock openings.
I know bipass doors aren't prehung. I've always install jambs first and then the door plus casing. Therefore the RO height has to be bigger than what he has. The width doesn't mater in his case because he can get smaller doors. That's if he's talking about bipass doors, what makes you think he is?
