Advice on a exterior door rough in
 
I have a exterior door that needs to be egress(3'by6'8"). I have no problem with my height but my width is 3' 1/4" with my king stud and jack stud. I can not move the king studs or jack studs because it is a door within concrete. I have not put the header,king studs(2by6), or jacks studs(2by6) in yet. So without my lumber in, I have a 3'6" opening. The doors at home depot, with trim already installed, require either a 38'1/4" or 38'1/2" rough in opening. So my question is how can I get that door in? What if I use the concrete as my king stud? Then I would save 3 inches.:thumbsup:. What if I forget about the trim and just install the door right to the jack studs but then I would only have a quarter inch to play with. Please help! Thanks.

Why king and jack studs in a concrete wall?? Supporting something above?? Header?? You can probably remove jack studs if you enlarge header. Having wood to anchor jambs to is always easier.

Hi there,
Are you sure about your R/O requirements?
Most 36" residential prehung door units are designed to fit in 38"x82" opening.

That aside, perhaps you could remove your jack studs and replace them
with a header hanger. Then fill in as needed for proper R/O width.
Check with inspector or engineer to make sure it is ok for your application.

Best of luck with fun door project!

Sorry can't get my 13.6 mp picture to a 100kb, required by this site. I tried cropping it the best I could but no luck. File still to big.
@ the door guy, I was told that the prehung doors rough in was bigger due to the manufactures recommendations. But they used to be smaller. So I am sure a 38" wide would work too. That header hanger definitely looks promising.
@Just Bill, Yes I am supporting two 2by8 floor joist. So i will need some type of header. My door is sitting right below my sill plate. As of right now 2 of my floor joist are sitting on nothing but a sill plate. Its got quite a bow going.:laughing: I was going to use a 3 2by8s and plywood sandwich to make my header.(5 1/2" wide).
I am either going to take away the king stud and just support the header with the jack stud. Screw the jack stud into the concrete. Maybe add the header hanger with the jack stud for extra support. I don't know. I will try to do some more research. Are these my only options?

Just cut the 16" and 32" joist back, add a header joist staying within 3' of bearing, no need to double: http://publicecodes.citation.com/ico...002_par031.htm

Gary,I understand the spans and whether or not to add a single trimmer or double trimmer but I dont understand the staying within the 3' of bearing. And I also don't see where you are getting 16" and 32". I am definitely missing something. Also attached a picture. Had to download Picasa.

Put the header on the sill plate, extending past the concrete on both sides. Cut the joists back and hold them in place with joist hangers on the new header. This way you can install one set of framing(pressure treated) against the concrete.

Thanks a lot Ron. That will work great! I will have plenty of room to add a door now and the weight of the joist above will transfer away from the trimmer joist. Took me a second to understand what you were saying. I couldn't comprehend putting a header there for some reason. Going to buy the hangers. Going to have to jack up a couple of those joist so I can get the header in. Thanks again. :thumbup: I am going to do this with my basement windows also. Already installed new blocking on the joist but taking them out and adding the header above the pt sill will give me more support and room there also.
