Easy to install, no tools required. Plug and play, then finish. Different wires are managed separately, different diameters can be safely connected. 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 ideal for removable connections as there is no no need to solder. Suitable for copper wire 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 threads, just lift the little lever and pull out what you need and replace, 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 electric 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 adjusted automatically with conductor thickness, conductor contact is reliable and not affected by installation technology.
