How it works and how to install
Cup-type terminal blocks allow two wires to be connected by inserting them into the 4mm hole and tightening the internal screw. The stripped wire is inserted into the open side, the screw is tightened with a standard screwdriver, and the connection is ready. The transparent body facilitates visual inspection of the contact. Suitable for copper wires with a cross-section corresponding to the 4mm hole.
