Abstract
Abstract An improved device for providing EMI/RFI shielding for a joint is disclosed comprising a compressible, resilient sealing element and a conductive shielding element bonded to the sealing element and positioned such that the shielding element provides a direct electrical contact across the joint. The disclosed invention further provides a cabinet which effectively utilizes such a device. The disclosed invention also includes an improved cabinet construction which minimizes the paths by which moisture and debris may enter the cabinet interior, while providing a cabinet which is transportable without violating the integrity of the cabinet structure.
