Door openings commonly have two king studs and two jack studs. A king stud is one that runs continuously from the top plate to the bottom plate.
This method is essentially the same as framing a door opening and filling in the lower area with jack studs and a sill that runs between two trimmer studs. Of course, for a door opening the bottom plate is cut out after the wall sections are tilted into place.
Step 9. Nail the king studs, jack studs, a header and a cripple stud in place to complete the rough door framing.
Where there is a doorway or a window, a special form of bracing needs to be done. The jack studs act like regular wall studs. They help brace the trimmers and the headers.
