ABSTRACT:
An adjustable door frame has adjustable width jambs and header. Each of the frame elements consists of two elongated components held together with interengaging rails and channels on the two components. In use, the frame elements are adjusted to the desired width and are locked in place with self tapping screws through the rails and channels. This allows the elements to be installed in a door opening in the same way as a fixed width door frame and without the use of screws through the door casing.
