Door frames, frame kits, component parts, jamb coverings, and depth extenders, all constructed with fiber reinforced pultruded structures, for entrance doors to buildings, both garage entrance doors and personnel entry doors. Some embodiments have a closed back wall. Others have an open cavity at the back wall to receive a reinforcing substrate. Some embodiments include a pultruded nosing block. Some embodiments comprise a pultruded depth extender, mountable on a jamb base to extend the depth of a door jamb. A mounting finger and a locking stud on the depth extender are mountable in cavities in the jamb base. A depth extender can be used to extend the depth of either a garage door frame or a personnel entry door frame. In an in-swing door frame, a door latch-side abutment surface is located on the side wall of the jamb base.
