An electrical ceiling box has an entrance port which is substantially closed by a cable clamp including an elongated tab hingedly connected at one end to a wall of the box. Near the other end of the tab is an arcuate wall extending from the inner surface of the tab. The wall has a concave surface facing toward the distal end of the tab. The concave surface is shaped and dimensioned to receive the end of a finger so that the installer can engage the tab to swing in into the box and insert a cable through the port. At the base of the concave surface is a recess shaped and dimensioned to receive the end of a screwdriver blade to allow a screwdriver to be used for opening the port.
