Abstract:
A system for closing both sides of an aperture extending through a vertical wall, the system comprising two identical assemblies placed vertically over the aperture on opposite sides of the vertical wall, each assembly comprising:a pronged grommet cap 12 having a substantially planar top side and a substantially planar underside, the pronged grommet cap 12 comprising: a flange 22 positioned at an outer edge of the pronged grommet cap 12 and having a diameter substantially larger than the aperture; a shank 20 depending from the substantially planar underside of the pronged grommet cap 12 and having an outer diameter substantially equal to an inner diameter of the aperture to be covered so that the pronged grommet cap 12 frictionally fits and is held in the aperture; a slot 24 cut into the pronged grommet cap 12 and extending through the flange 20 to the outer edge of the pronged grommet cap 12; and a receiver 34 comprising: a first prong directly attached to and depending downwardly from the substantially planar underside of the pronged grommet cap 12; a second prong directly attached to and depending downwardly from the substantially planar underside of the pronged grommet cap 12, the second prong spaced from the first prong by a prong separation distance, the first and second prongs forming therebetween a first downwardly facing open space; a third prong directly attached to and depending downwardly from the substantially planar underside of the pronged grommet cap 12; a fourth prong directly attached to and depending downwardly from the substantially planar underside of the pronged grommet cap 12, the fourth prong spaced from the third prong by the prong separation distance, the third and fourth prongs forming therebetween a second downwardly facing open space; a disengageable tab means sized and shaped to fill the slot 24 and having a male connector with an elongated cylinder 32, the elongated cylinder 32 being of a diameter substantially equal to the prong separation distance, the elongated cylinder 32 being located in and extending between the first and second downwardly facing open spaces and held by the receiver 34 in a manner permitting pulling with mild force the disengageable tab means out of engagement with the pronged grommet cap 12 so that the disengageable tab means can be separated from the pronged cap 12.
