NineLeaf CONN-B-180PK-SET 180-Piece Lever Wire Connector Kit, 28–12 AWG

For wiring jobs where quick, accessible connections matter, lever connectors offer a different approach from twisting conductors together and securing them with tape or solder. The NineLeaf CONN-B-180PK-SET brings several connector sizes together in one organized kit, so you can select a two-, three-, five-, or one-port option for the connection at hand.

The clear housings make wire placement visible, while the levers open and close the connection without a tool. It’s a practical format for lighting work, junction boxes, switches, and other wiring projects that call for joining compatible copper conductors.

Why it makes sense

This 180-piece assortment gives you a mix of connector configurations for different wiring layouts: 80 two-port, 65 three-port, 25 five-port, and 10 one-port connectors. That range is useful when a project involves both straightforward wire-to-wire joins and connections that bring several conductors together. The compartmented storage box keeps the assortment organized and portable, making it easier to find the configuration you need at a workbench or on a job.

Each connector uses a lever push-in design: lift the lever, insert the wire, and close it. There’s no need to twist conductors together or use tape or solder for the connection. Stainless-steel spring clamps hold the wire, and the transparent housing gives a view of its placement. Rear test holes provide access for voltage checks without taking the connection apart.

What to know

The connectors are designed for solid, stranded, and flexible copper wires from 28–12 AWG (0.08–4 mm²). The stated maximum voltage is 250 volts, and the product is described for low-voltage and standard 110–250V applications. Its insulated housing is made from flame-retardant, corrosion-resistant materials, with stainless steel listed for the contact material.

The assortment suits a range of practical wiring tasks, including ceiling fans, lighting fixtures, switches, junction boxes, sockets, speakers, and control systems. Choose the port count according to how many conductors need to meet at a connection, and use the connector only with compatible copper wire and within its stated voltage rating.

How to use it

Lift the lever, insert the compatible wire, then close the lever to secure the connection. The visible housing helps you check the wire’s position, and the rear test hole can be used for voltage checks without dismantling the connection. Keep the different port counts sorted in the included compartments so the right connector is easy to reach as you work.

Practical questions

How many connectors are in each configuration? The kit contains 80 two-port, 65 three-port, 25 five-port, and 10 one-port connectors, for 180 pieces total.

What wire types can these connectors take? They are specified for solid, stranded, and flexible copper wires in the 28–12 AWG (0.08–4 mm²) range.

Can the connectors be reused? They are described as reusable multiple times. Open the lever to release or reposition a wire, then close it to secure the connection again.

Buying verdict

For electricians, technicians, and homeowners handling wiring tasks, this kit combines multiple port counts, a visible lever-operated connection, and organized storage in one assortment. It’s especially useful when a project includes several kinds of wire joins and you want the connector configuration close at hand.
