I am installing two 3ft shed doors into a 6ft opening. I have some pressure treated 1x6s to make the door jambs.
- I cut the door jamb header to run across the 6ft length and screwed to the door framing above.
- I then cut the door jamb sides and screws those to the sides of the door framing.
Then I got to thinking maybe the door jambs should but against the sides of the top jamb so it reduces the spreading of the jamb from the heavy shed doors (made from solid 1x6s).
What is the correct setup for this? Does the door jamb head provide any lateral structure support for the side jambs hence should go between the door jamb sides?
