Good Safety Performance: Made of the finest Nylon flame retardant insulating material. With the advantages of long service life, corrosion resistance, aging resistance, high pressure resistance, insulation and flame retardant, it can effectively prevent electric leakage. So the lever nuts are safer than traditional thread nuts. High Quality Internal Material: The inner shrapnel is copper material, special surface coating preventing 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 is not affected by installation technology. Easy to Use: Easy to install, it is not necessary to use tools. Just plug and play, then done. Each junction independent shrapnel, different wire managed separately, different diameter can be safely connected. Built-in test point, electrical test without removing the tape. Technological innovations reduce wiring time by more than 50%. Widely Application: It is widely applied to building wiring, such as that used to control multiple lights by one switch. It is ideal for compact and complex applications. Practical: They are ideal for removable connections as there is no need to solder. Suitable for 0.08-4mm / 28-12 AWG copper wire. Connect any combination of solid, stranded and flexible copper wire faster and more reliably. If you need to change other wires, just pull up the small lever and pull out what you need and replace it, which is very convenient.
