Abstract
A door-hanging jack for adjustably supporting doors in door openings while installing doors in building structures. The jack structure has a generally triangular base with a pivoted rectangular framework secured to the top and has a structural angle shaped door-supporting member on one side overlying one edge of the triangular base. A threaded member at an apex of the triangle provides movement of the door supporting member through the interaction of a female threaded member having foot engageable handles.
