Which part of a doorway is responsible for securing the door to the studs in a building?

The jamb of a doorway is the component that secures the door to the studs in a building. It consists of the vertical parts on either side of the door frame and provides the structural support needed to hold the door in place. The jamba are crucial for ensuring the door operates properly, allowing it to swing open and closed smoothly while also maintaining the integrity of the door's position within the frame.

The header, which is located at the top of the door frame, primarily serves to support the weight of the structure above the door, rather than securing it to the studs. The threshold is the bottom strip of the door frame that may provide a seal and aid in energy efficiency but does not secure the door to the studs. The overall frame includes all components, but it is the jamb specifically that provides the necessary connection to the wall structure. Understanding these components is important for assessing the construction and functionality of doorways in building inspections.
