Our standard geodesic dome door is a Fabric Door and can be opened and zipped closed from the inside or out. It can be rolled up and tied open. The 16 ft. geodesic dome door is 4 ft. tall by 2 ft. wide. The 20 ft. to 60 ft. geodesic domes have a diamond shaped door hole approximately 6 ft. tall by 3 ft. wide. Our Pre-Hung Door Option allows for a normal opening and closing/lockable door installation. Shelter Round Hoop Doors for your geodesic dome can also be used to connect two or more domes.
