Now my next task is installing theater door. My rough opening height is just 81.5", I got an 80" solid core slab, door header board takes 3/4", so just about 1/2" gap left between the bottom of the door and unfinished concrete floor, that seems to be not enough, plus, I want to install a door threshold to seal the door when it is closed.
Here is the jamb and header board I installed:
From outside looking in:
From inside looking out:
This is the slabs, I got two, one from HD, 36"x80", one old slab, has some damage on corner, 35 3/4"x79 1/2", both solid core heave slabs, about 50lbs maybe:
The door threshold, as you can see, it is for exterior door, and it is about 1.5" tall profile, so if I install the threshold, means that I need to cut slab short about 2":
Threshold placed in the door opening:
Another question, do you install slab directly on concrete floor? If so, the one I have has no hole, it was originally stapled on to the two side door jamb. So I need to drill 3 holes on the aluminum and screw down to concrete floor that way? I need some advices here.
About cutting slab door, after cut, the bottom will be unfinished, so what do you do?
