Abstract
Abstract A face plate with an elastomeric, electrically-conductive gasket to provide electromagnetic radiation and control air flow for a front panel of an electronic equipment frame. The metallic face plate has a plurality of edge surfaces which are capable of providing electrically conductive contact with the frame wherein one of the edge surfaces has the gasket. The gasket is an electrically-conductive contact with the face plate and an adjacent face plate which forms a thermal seal and an electrically-conductive surface.
