Abstract
A method is described for providing selective communication between two enclosures. The first enclosure includes a first flange and a first door. The second enclosure includes a second flange and a second door. The method includes performing sequentially the steps of arranging the second flange on the first flange, axially maintaining the second flange on the first flange by snap-fitting, securing the first flange to the second flange, securing the first door to the second door, releasing the first door from the first flange, releasing the second door from the second flange, opening the first door relative to the first flange, closing the first door relative to the first flange, securing the first door to the first flange and securing the second door to the second flange, unlocking the first door from the second door, and separating the first door from the second door.
