A door frame component is provided. The door frame includes: a front wall, a rear wall, an outer wall and an inner wall; a length of the front wall being substantially the same as a distance between the inner wall and the outer wall; an internal cavity at least partially defined by space between the inner wall and outer wall; and opposing first and second gripping sections defined in the internal cavity at least partially by first and second internal flanges in the internal cavity. The frame has sufficient structural integrity such that when the frame is cut height wise between the first and second internal flanges into front and rear sections, the front section can support a door on its own without the rear section.
