The MCLAD: Monolithic Contoured Laterally Moveable Access Door

Door’s track — Instead of inside, the track from which the Monolithic Door hangs can be installed on the dome’s outside. “That’s another advantage,” David pointed out. "That makes it possible to construct a huge Monolithic Dome or Crenosphere as a stadium, for example, and equipping it with a Monolithic Door that, when opened, turns the facility into a huge amphitheater.

Perfect fit — What was invented as a hangar door did not remain just a door for hangars. “As we continued to work with this idea, more uses and possibilities began occurring,” David said. “Because this door can be shaped and sized to fit a specific need, it will work well for shops, factories, garages, storage facilities — even huge stadiums and amphitheaters.”
