In framing the space provided for a door, door jamb and space for adjustment is known as the __________.

• A. header
• B. buck
• C. rough opening
• D. balloon

Answer: (C)

When you frame a doorway, the space set aside to receive the door assembly—including the door jamb and the room for shims and adjustment—is the rough opening. It’s intentionally larger than the finished door so you can square and plumb the jamb and properly fit hardware. The header is the horizontal support above the opening, a buck is a door frame component used in some constructions to form the rough opening, and balloon framing refers to a wall framing method. So the opening itself is the rough opening.
