A hole plug includes a main body having an inner surface, a perimeter, and which further includes a center axis that is substantially perpendicular to the inner surface and defines an axial direction. Additionally, a securing member extends axially from the inner surface and includes a base directly secured to the inner surface of the main body and a cantilevered protuberance at least partially axially spaced from the inner surface. Furthermore, the protuberance at least partially extends along a circumferential path that is a parallel curve of the perimeter positioned inward from the perimeter.

A pressure relief assembly includes a housing defining an air passage chamber having at least one opening, and a flap secured within the air passage chamber. The flap is configured to move into an open position to expose the opening(s) to relieve air pressure. At least one liquid diverter extends from the housing. The liquid diverter(s) is configured to direct moisture away from the flap.
