Abstract
An enclosure having an improved seam for inhibiting passage of electromagnetic radiation through the enclosure is described. The enclosure having a housing and a removable cover are joined at its respective edges. A plurality of spaced-apart tabs extend from an edge and slideably engage a plurality of slots which are formed on an interior surface adjacent to a corresponding mating edge. A domed projection on each tab slides into recessed cavities located on each slot to form a tight mechanical connection. The enclosure has a metal-coated interior surface and mating surface, wherein the tabs and slots operate to electrically couple the cover to the housing.
