A recess extends into the channel at the inner edge of the first door, from an inner surface, the recess admitting the low wall of the continuous gutter or channel. A slot in the inturned inner edge of the second door fits over the recess in the channel at the inner edge of the first door. Gaskets can be Provided to enhance sealing. The structure can be repeated for the bottom of the door opening. For an enclosure, the double door structure can be on one side or both sides. Latches provide a closing force to enhance sealing.
