<p>A door support frame 4 has two adjustable screw legs 1 each with a base plate 3 and a handle 2. The height of the legs may be fixed by the tightening of a locking nut 5. In use the door is placed in the frame, with the frame fitting under the base of the door, and secured by the use of a wedge 6. The door, with the attached frame, is positioned in the door frame and the legs adjusted allowing the hinged door to be securely screwed to the door frame.
