Automatic Door Bottoms

Automatic door bottoms mount to the bottom of a door and seal to the threshold when the door is completely closed. How does it work? When the door is closing, the horizontal protruding operating rod strikes the door jamb, causing the movable plunger "horizontal bar with gasketing" to drop, thereby actuating the plunger function pressing the gasketing to the threshold.
