The inlets are scalable depending of the diameter of the cable. This connection box is very useful when using thick cabler or when more than two cables are to be met. Note that the center screw goes through the connection box which prevents putting a dimmer card in this box.
The inlet holes are made of hard plastic that can be cut to accommodate the cable. This beautiful connection box is very useful for mounting thick cables or housing more than two intersecting cables. Please note that the middle screw goes through the entire connection box, which means dimmer cards cannot be used inside.
