(pronounced RUHF OH-peh-ning)

A construction term meaning the wall opening into which a frame is to be installed. This could be for a door, window, paper towel dispenser, ventilation grille, electrical panel… We could go on and on. The space must be slightly larger then combined size of the item and the frame. Sometimes you’ll see the term abbreviated as R.O.
