Door units, without pre-hanging, are also called “slabs”. We sell single doors or in pairs (french doors).

French Door, 2-Panel Arch, ‘SEGMENTED’ (below)
Active French Door with Astragal and Slide Bolt (below)
In the above case, you’ll choose one of doors as “Active”, with a working lockset. The other door of the pair is inactive (still opens and closes, but no working lockset, you will need a dummy), this choice will automatically include a “T-Astragal” attached to the door edge for latching the active door. Flush bolts (top only is defaulted, however you can select two if they request an additional slide bolt in the floor)
