A faceplate having at least one opening with a cover. The cover may be removed after initial use of a circuit board to be replaced with a connector unit through which conductors may extend to the circuit board to allow for its modification in operation. This enables the same faceplate to be used for modification purposes and without the expense entailed with a faceplate of different design. The cover may be such as to completely cover the whole of the opening. Alternatively, the cover may be provided by a connector unit which enables interconnection of conductors through the faceplate in one part of the unit while providing, in another part of the unit, the cover for part of the opening. This connector unit may then be replaced in the modification by another connector unit which enables connectors to extend and be connected through the whole of the opening. Conveniently, a latching arrangement is provided for assembly and disassembly purposes for both the cover and connector unit with frontal access. This provides speed of operation with no loose parts required. Also included is a method for providing the inventive modification.
