I've been waiting for this since I first discovered lever lock connectors. You can use them to produce terminal blocks of any desired length without the use of tools. MARVELOUS! The only thing missing is a way to hold them in place. A clamp or some sort of rail would be ideal, but hot glue works well for now.
