Easy to install, no tools required. Plug and play, then finish. Different wires are managed separately, different diameters can be connected safely. Built-in test point, electrical test no need to remove the tape. Instead of traditional electrical tape and twist-type electrical butt connectors, technological innovations reduce wiring time by more than 50%. They are perfect for removable connections because there is no no soldering required. Suitable for copper wires of size 0.084 mm / 2812 AWG. Connect any combination of solid, stranded and flexible copper wire faster and more reliably. If you need to change other wires, you just flip up the little lever and take out what you need and replace it, which is very convenient. Made from the best Flame retardant insulation material Nylon PA66. With the advantages of long service life, corrosion resistance, aging resistance, high pressure resistance, insulation and flame retardant, it can effectively prevent electrical leakage. Lever nuts are therefore safer than traditional metal nuts. The internal spring contact is made of copper, a special surface coating to prevent oxidation, low resistivity and better conductive properties. Spring clamp technology is reliable and does not fall off. Since the clamping force can be automatically adjusted with the thickness of the conductor, the contact of the conductor is reliable and is not affected by installation technology.
