<p>A clamp (10) for clamping a door (16) has first and second clamp surfaces which define a jaw for clamping each face of the door; the surfaces being moveable with respect one to another, so as to accommodate doors of different widths; a baseplate in which the clamp surfaces are supported and able to move with respect to one another and a locking means for locking the clamp surfaces when desired. In a preferred embodiment the base plate of the clamp is sufficiently thin so as to enable the clamp to be placed below the door. Ideally the baseplate and each of the clamp members are demountable so as to enable the door clamp to be disassembled and packed suitable for storage or transport. An advantage of the clamp is that assists fitting of a door.</p>
