Abstract
A door frame assembly is made of first and second aluminum extrusions which may be placed in a door opening in wall after the wall has been completely finished. The structure of the frame assembly inherently compensates for variations in wall thicknss and dimensional errors in the door opening dimensions. Steel anchor plates are fastened to the wall in the door frame opening and the assembly is attached to the anchor plates. Once the completed assembly is in place, all of the attaching members are concealed from view.
