The upper part of the device is designed to be mate with the upper part of a wall box having cable entry slots(holes). The lower part of the device includes the cable guidance tool in the formed of a 90 degree curved duct. The two parts can be moved away from each other by a pressure maintained cam. The device has an upper movable part(1) through which the cables pass, which can be raised by handgrip(5) acting on a cam(7) causing an increase in the diameter of the device. The lower part of the device has a 90 degree angle duct(3) with curved sides(4,10),which guides the cable bunch through the device.
