A panel hole closure is composed of a rigid plate having an integral array of resilient fingers projecting from one surface of the plate inboard of the plate rim. A integral stiffener is provided for each finger which stiffens the finger against inward deflection toward the axis of the plate so that once the closure is seated in a panel aperture, it is difficult to dislodge. A plastic sealing ring encircling the plate rim may be melted and flow to provide a fluid-tight seal between the closure plate and panel. |
