A door jack to facilitate the installation of doors. An elongated pry-bar is provided having a pry-foot at its lower end. An elongated stabilizing rod is provided having a pad on one end. A sleeve is secured to the upper end of the pry-bar and reciprocally receives the stabilizer rod which extends forwardly therefrom in the same general direction as the foot. A coil spring surrounding the stabilizer rod biases the rod and pad outwardly away from the pry-bar. A lock washer on the stabilizer rod locks the same against inward movement from a selected position. The foot may be inserted under the bottom edge of a door and the pry-bar pivoted rearwardly thus elevating the door to the desired elevation for hanging the same. In that position, the pad on the end of the stabilizer rod engages the surface of the door under the influence of the spring, the lock washer preventing rearward movement of the pad and stabilizer rod. Thus, the door is maintained in the desired elevated position for installation of hinges, etc. The jack may also be used for carrying the door to the installation site.
