Abstract: A cabinet is shielded against electromagnetic interference. The openable door thereof is sealed by conventional fingerstock. The door includes a forward-facing blade-like flange all round the door, and the fingerstock is so placed in a recess in the door frame as to wipe the sides of the flange, as the door is closed. The door is provided with two hinge pivots, connected by a bar: over the last portion of the door closing movement the door is thereby able to travel in an (almost) straight line into the door frame. Four latch assemblies, operated by a manual door handle, are provided, and include cams to assist in drawing the door into the frame.
