I'm building a new master bedroom closet. The wife wants a specific 30x80" door which requires a rough-in of 32x82. Unfortunately, the measurement from the top plate to the subfloor is 83 1/4". I'm not sure how to handle this. The jack studs for the rough-in would be 82" which would mean no top plate would fit (A 2x4 is 1.5" thick and I only have 1.25" available).
Do I just not put a top plate, make the jack stud 83 1/4" and just deal with the extra 1 1/4 at the top of the pre-hung casing? Do I try to trim the 1.5" of the top plate down to 1.25" somehow?
