Abstract
Abstract A chassis-panel assembly including an insulator grommet or spacer for securing the panel spaced apart over the chassis, and wherein said grommet includes a spacer body, a spreader block and securing wings. To assemble, the spreader block and wings are projected through an aperture in the chassis and a headed screw is extended through an aperture in the panel and engaged in the spreader block to draw the spreader block into the body and force the wings outwardly under the chassis until the screw head is seated tightly against the panel.
