Features: Safe and ReliableThe lever wire connector is made of flame-retardant insulating material PC, which has a long service life, no corrosion, anti-aging, pressure resistance and electric shock resistance. Using flame retardant material, internal copper material, better electrical conductivity, can work continuously at 221 degrees Fahrenheit. Space SavingThese lever wire nut connectors are specially and scientifically designed to save space effectively. And when you combine wires, you don'for t need to worry about twisting between wires. Easy to useFirst, strip the wire according to 9-10mm, then push the orange pull rod to 90 and push the wire in, and finally push the pull rod down. When the wire is inserted into the lever electrical connector and locked, the wire will not come loose. Wire terminal connectors are highly resistant to pulling. Time-saving and labor-savingThese splice wire connectors can quickly connect and remove wires. If you want to replace a wire, just pull-up the orange lever, pull out the wire you don'for t need and replace. There is a test hole on the surface of each wire connector, which can be used to check whether the wire has electricity. Widely UseLever wire connector kits can meet your different wiring needs as they have 8 different conductors (2 3 4 5 6 8 10 12 ports). They can connect any combination of 28-12AWG solid, stranded and flexible copper wire. Wire connectors are commonly used in sockets, switches, lamps, electrical boxes, chandeliers, automobiles, speakers, fan controls, etc. Specifications: Material: Plastic Weight: 60g Size: As picture shows Type: 22-2/22-3/22-4/22-5/22-6/22-8/22-10/22-12 Note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
