Abstract:
1. A door panel and door insert for equalizing air pressure in a closed environment, comprising: a door panel having a front face and a bottom edge; the bottom edge of the door panel defining a notch emanating inwardly therefrom; portions of the edge on opposing sides of the notch respectively defining a left tab receiving surface and a right tab receiving surface; the left tab receiving surface and the right tab receiving surface being perpendicular the front face of the door panel; a frame having a bottom wall, a front wall, a back wall, a first side wall and a second side wall; the front wall and the back wall being in spaced apart and substantially parallel relationship to each other; the first side wall and the second side wall interconnecting the front wall to the back wall; the first side wall and the second side wall being in spaced apart and substantially parallel relationship to each other; the front wall, back wall, first side wall and second side wall defining a slot; the bottom wall being connected to the front wall, back wall and first and second side walls to define a floor; the bottom wall having a left side and a right side; a fixed left tab connected to and emanating laterally outward from the left side of the bottom wall and being in the same plane therewith; a fixed right tab connected to and emanating laterally outward from the right side of the bottom wall and being in the same plane therewith; the frame, fixed left tab and fixed right tab being configured and arranged as a single unitary member; media having a plurality of apertures therethrough; the media residing in the slot and supported by the bottom wall of the frame; the frame, with the media installed therein, being configured and arranged to reside within the notch; the frame and media therein being secured in the notch by the fixed left tab being secured to the left tab receiving surface of the door panel and the fixed right tab being secured to the right tab receiving surface of the door panel; and whereby air is permitted to flow through the door insert to equalize the air pressure within an environment divided by the door panel.
