The head is the horizontal top member of a hollow metal door frame, spanning between the two jambs above the door opening. It carries the strike-side and hinge-side jambs into alignment, closes off the top of the rough opening, and gives the door its stop line across the head.

Steel frame heads of this type are formed with the same profile as the matching jambs - face, throat and integral stop - so the assembled frame reads as one continuous section once the corners are joined. Knock-down frames are shipped as separate head and jamb pieces and put together in the opening, which makes a replacement head useful when an existing frame is damaged or when a frame is being built up on site.

The throat dimension is the critical fit measurement: it has to match the finished thickness of the wall the frame is set into, and it has to match the jambs it is joined to.
