Abstract: A door frame shield to extend about and longitudinally of the inside surfaces and the front and rear edges of a jamb and door stop and outwardly about the front and rear casings of a related door frame structure. The shield includes elongate front and rear inside sections of extruded plastic to engage about and extend longitudinally of the jamb and door stop; and, elongate retainer parts of extruded plastic to engage about and extend longitudinally of the front and rear casings of a related door frame structure. The front and rear inside sections and the front and rear retainer parts are connected together by longitudinally extending fastener devices that allow for the sections and parts to be moved into tight substantially conforming engagement with and about the jamb, door stop and casings with which the shield is related.
