Abstract: The invention is a system that prevents the opening of a door into a room or other area by an intruder. The system includes an aperture positioned in flooring, the aperture located adjacent to a first side edge and bottom edge of a closed door. The system also includes a block comprising an internal passageway with about the same dimensions as the aperture. The system further includes an elongated pin comprising a first end and a second end, wherein the pin is configured to pass through the block internal passageway and into the aperture. The block is held in position over the aperture when the pin passes through the block internal passageway and into the aperture. When the block is held in position, the closed door is prevented from opening.
