An inner cover 5 is provided that may have a projection to divide the box 4 into two or more compartments. The screws 6 that secure the cover 5 have hollow heads 7 into which a pin on the screw-driver fits to prevent slipping. A hook for suspending a fitting may pass through a tube 10 into the beam above.
