Abrégé

A pre-formed header assembly creates a rough wall opening for a metal door/frame, permitting completion of electrical, ducting, drywall, etc. prior to receiving/installing the door frame. The header is secured to first and second king studs at respective locations positioned beyond a desired door frame location. The header includes four different channels, one of which is utilized at two locations. The first channel has a first length to span between the king studs. The second channel has a second length, and the third channel a third length, which correspond to minimum dimensional requirements for completing the wall. The base of the second and third channels are each fixedly secured to the base of the first channel. The base of the fourth and fifth channels are fixedly secured to the first and second ends of the base of the first channel, respectively, substantially perpendicular thereto, for attachment to the king studs.
