How many times have you had to loop one side of a terminal strip (chocolate block) to give you a few common terminals. It's always looks messy and is usually a point of connection problems in the future, and also takes up valuable time.
Now we have the answer for you, a small terminal block 45 x 28mm with 14 screw terminals all connected on the underside of the PCB. Ideal for localised common Negative or Positive, or remove the link and it converts into a dual polarity terminal block. Place the board where  you need to join half a dozen wires together for some reason.
