The fireproof door sealing strip is installed inside the bottom of the fireproof door. When the door is closed, it will automatically extend the movable seal downward to press the ground and close the gap between the bottom of the door and the ground. The fire door sealing strip prevents toxic smoke from entering the room through the gap at the bottom of the door at the beginning of the fire.
