A door hanger device having a horizontal support structure having rollers mounted on the bottom thereof and clamping vise-like structure on the upper surface for clamping and holding at least two doors simultaneously. A vertical support structure is securely fastened to one end of the horizontal support structure and diagonal bracing between the horizontal support structure and the vertical support structure is provided for greatly increasing the overall strength of the device. Door clamping structure similar to the structure mounted on the horizontal support is also provided for the vertical support structure and the vertical clamp devices are adjustable vertically along the vertical support structure. A screw thread being operated with a proper ratio gearing is provided for changing the vertical adjustment of said clamping devices. The horizontal support structure forms a generally U shape so that three doors may be transported and held simultaneously without interfering one with the other. The invention also envisions extension structure for both the horizontal and vertical supports. These extensions will greatly increase the capacity and versatility of the overall device. The extensions also have door clamping vise-like structures mounted thereon and the vertical extension has another screw-threaded adjustable means for varying the vertical position of the associated clamps.
