Framing & StructuralQuestion 307 of 700
In header framing, what is the difference between a king stud and a jack (trimmer) stud?
a.The king stud runs full height beside the opening; the jack stud is cut to support the header end
b.The king stud supports the header; the jack stud runs full height
c.Both run full height and neither supports the header
d.The jack stud is always doubled and the king stud is never used
Explanation
The king stud extends full height from plate to plate alongside the opening and is nailed to the header for lateral stability, while the jack (trimmer) stud is shorter, nailed to the king stud, and directly supports the underside of the header end. The other statements reverse or confuse these roles.
