A door head is the top part of a door frame, located above the door itself. It helps support the structure of the door frame and provides a finished look to the entrance. The door head can also include additional elements, such as decorative molding or a beam, which is a horizontal support that helps distribute weight from above. This part of the frame is essential for ensuring the door operates properly and maintains stability, contributing to the overall strength and appearance of the doorway.
