Had ordered for extending a ground cable 5x1.5 me the connection box. The items made a good and robust. The problem appeared then on the jam. The screws are made of a rather soft material, you have to be careful that they are not damaged. The space is very cramped and it is difficult to accommodate the rigid circuit. When screwing I realized then that the mother was wrong on one side. If the part is no longer for sale. If you have a little more space, simply use a small terminal box with attachment bushes.
