In typical door framing, which framing member runs along the full height of the door opening and helps support the header?

• A. Sill
• B. King stud
• C. Cripple
• D. Trimmer

Answer: (B)

The framing member that runs along the full height of the door opening and helps support the header is known as the king stud. King studs are vertical pieces that provide structural support for the header above an opening, such as a door or window. They are anchored to the floor and extend up to the top plate of the wall, ensuring the header has the necessary support to bear the weight from above. This stability is crucial as it helps transfer loads down to the foundation of the building. Other framing members, such as the sill, serve different purposes. The sill is typically the bottom horizontal part of the frame that sits on the floor, while cripple studs are shorter vertical members placed between the top of the door opening and the header, providing additional framing support but not running the full height. The trimmer, also known as a jack stud, supports one end of the header, but it is not a full-height member; rather, it often extends from the header down to the bottom plate of the wall. Understanding these distinctions is vital for recognizing the roles of various framing members during construction.
