Protective door systems are presented for equipment enclosures in which an inner door is provided to resist outward opening pressures by facing or abutting one or more interior surfaces of an enclosure opening, with an optional outer panel covering the enclosure opening from the outside, where a closure mechanism is operated by an externally rotatable handle to initially back the inner door away from the enclosure front side and then to move the inner door upward at an angle to effectively clear two edges of the opening to allow pivoting of the inner door to an open position extending partially outside the enclosure opening.
