Although I renovated it, I used the thing that was attached before the door as it was. To fix the door is a type that crouchs and fixes by hand. If you are caught in the wind when you are not fixed, it is hard to play battle buttans. ST Door hidden double seated with a double seat Automatic (breadth) is fixed even if it is not fixed but winded by wind. I am satisfied that it is making solid thing on the whole.
