Product Material: pure copper conductorSize: 39.5*14.5*20.5mmQuantity: 10 piecesPackage Contents: 10*Wire Connector1.Good Safety Performance: Made of the flame retardant insulation 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. Thus, lever nuts are more secure than traditional thread nuts.2.High Quality Internal Material: Internal shrapnel is copper material, special surface coating preventing oxidation, low resistivity and better conductive properties. Spring clamping technology is reliable and does not fall out. 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 the installation technology.3. Easy to Use: Easy to install, no tools required. Just plug in and play, then done. Each junction independent shrapnel, different wire managed separately, different diameter can be connected safely. Built-in test point, electrical test without the need to remove the tape. Technological innovations reduce wiring time by more than 50%.4.Widely Application: It is widely applied to building wiring, such as used to control multiple lights by one switch. It is ideal for compact and complex applications.5.Convenient: They are great for removable connections as there is no need to solder. Connect any combination of strong, stranded and flexible copper wire faster and more reliably. If you need to change other wires, just pull up the little lever and pull out what you need and replace it, which is very convenient.
