The partially preassembled split doorjamb assembly includes first and second side bases substantially parallel to one another and a header base substantially perpendicular to and interconnecting the first and second side bases. The door is arranged within a space defined by the first and second side bases and the header base of the partially preassembled split doorjamb assembly so that the door, the first and second side bases, and the header base collectively establish a cavity. The first and second side extensions and a header extension are unassembled with respect to and connectable lengthwise to the first and second side bases and the header base, respectively. The extensions may be stowed within the cavity and/or stored on outer surfaces of the bases. ## Claims ### Claim 1 A door unit in kit form, comprising: a partially preassembled split doorjamb assembly comprising first and second side bases substantially parallel to one another, a header base substantially perpendicular to and interconnecting the first and second side bases, and extensions;
