I have several of these and dont have to worry about having enough sockets for all those extension leads you carry for instance down one side of the stage i can have my speakerplugged into a 6 stairville splitter also my 2 dmx lights that are connected into a 3 stairville splitter witch in also plugged into my 6 splitter and to finish is my par 56 stage flush plugged into the 6. and its set up the same on the other side then they come and join up on my 5m stairville extension which plugs into the wall and everything works really well i could not imagine going back to british plugs and extension cables using stairville products is so simple
