Easy to install, no tools required. Plug in and play and you’re done. Different wires are managed separately, and different wire diameters can be safely connected. Built-in test points eliminate the need to remove tape for electrical measurements. Technological innovations have replaced traditional electrical tape and stranded electrical end connectors, reducing wiring time. They are great for joining as no soldering is required. Fits 0.084mm/2812 AWG size copper wire. Connect any combination of strong, stranded and flexible copper wire faster and more reliably. If you need to replace other threads, just remove the small pull rod and take out the thread that needs to be replaced, which is very convenient. Made of the best material nylon PA66 flame retardant insulation. It has the advantages of long life, corrosion resistance, aging resistance, high voltage resistance, insulation, flame retardant, etc., and can effectively prevent leakage. Therefore, lever nuts are safer than traditional metal nuts. Internal spring contacts are made of copper with a special surface coating to prevent oxidation, low resistance and better conductivity. The spring clamping technology is reliable and does not fall off. Since the clamping force can be automatically adjusted with the conductor thickness, the conductor contact is reliable and is not affected by the installation process.
