ABSTRACT:
A weathertight and EMI shielded door configuration for a cabinet (10) includes at least one door opening defined by an upper, a lower, and two vertical frame members (34, 36, 38, 40, 42, 56). An upper, a lower and two vertical door skin members (90, 102, 94, 106, 110, 111) are bonded to door frame members (34, 36, 38, 40, 42, 56). The door skin members (90, 102, 94, 106, 110, 111) are formed to substantially cover the upper, lower, and vertical frame members, and defines a door recess having a depth and a substantially vertical and planar door-frame mating surface. A door (16, 18) having a thickness substantially equal to the depth of the door recess is hung in the door opening. The perimeter of the doors interior surface meets the upper, lower and two vertical door skin members (90, 102, 94, 106, 110, 111) at the planar door-frame mating surface. An EMI and environmental gasket (98) is positioned at the door-frame mating surface. In a double door configuration (120), the door sections (122, 124) meet at a planar and elongated door-door mating surface that is also sealed with an EMI and environmental gasket (138, 142, 132).
