Abstract
A door frame made up of two jamb sections and a head section connected together to fit into a rough door opening. The sections are each made up of an elongated, generally channel-shaped member having two spaced legs and an elongated, generally Z-shaped member having a flat surface disposed parallel to the legs of the channel. Surfaces of the Z-shaped member are supported in spaced, parallel relation to the surfaces of the channel member, providing spaces to receive wall material therebetween.
