The head is the horizontal top member of a knock-down hollow metal door frame, spanning between the two jambs above the door opening. It carries the same profile as the jambs so that the stop, rabbet and soffit run continuously around the opening once the frame is assembled.

Knock-down steel frames ship as separate head and jamb pieces that are mitered or notched at the corners and joined on site, which makes individual replacement members useful for repairs, retrofits and making up odd openings. The head is set first, tied to the jambs, then plumbed and squared before the wall is closed up or the frame is grouted.

The 3-7/8 in. dimension is the throat depth of the profile, sized to sit over a wall assembly of matching thickness, and the 36 in. dimension corresponds to a standard single-door opening width.
