At this point, you will require an assistant to hold the door in place while you screw it. After screwing the door in place, check whether it is plumb (vertical) using a level.  Note that, the door casing could not be plumb, however that doesn’t affect the door, your attention should be on the door.

Also called rail, a drip cap is a short metal plate put above the exterior doors to prevent water from infiltrating behind the door frame. Use caulk to hold the drip cap firm. Use the drill and the screws to screw the rail into the front of your entry door casing.

Finally, fix the handles, strike plate, and closers and test your door.
