Door Jamb and Moulding as Load Bearing?
It’s not structural. It’s just a design we use for “clean lines” without the grooves and notches in the trim, etc.
If you were to remove the entire frame, you’d see that there are shims along the head and jambs. Any structural load can’t be transferred to the jambs if there’s shims in the head, AND the frame can’t be “squared” without the shims.
This design makes the frame look more like hollow metal frames...
