A clamping device is disclosed for holding doors, panels and similar generally planar workpieces in an upright position while the device is attached to a stationary or movable support. Automatic clamping of a workpiece is accomplished by placing the workpiece on a support member and in contact with a movable member, with the weight of the workpiece causing diagonal sliding movement of the workpiece and movable member towards a stationary member. The workpiece is released by lifting the workpiece, with a coil spring urging the movable member diagonally away from the stationary member.
