King Innovation 95035 AlumiConn wire connector, 100 pk, Purple

These are brilliant. Ever try to wire a light fixture with tiny stranded aluminum wire normal gauge household copper wiring?? It’s difficult unless you are a pro electrician. And the wire connectors sold for aluminum to copper are too big for a small aluminum strand to household copper. These make the task simple,secure and much safer in my non expert opinion. Most people also don’t know that aluminum to copper connections require a antioxidant lubricant on both wires. These connectors already have it filled in the holes.Awesome product. They only improvement I see that could be made is the price!!! YIKES!! And the fact that you MUST torque the screws to 15 foot-lbs using a torque screwdriver. I had one. You would be amazed how much torque 15 foot lbs is. Great product. I gave it 5 stars but due to the price it’s really 4.5. But I would buy them again anyway

The connectors take up a large amount of room in an electrical box already stuffed with number 12 AWG wire.Having said that it is a much better solution than a twist on connector

A good solution for aluminium to copper transitions. Trust them more that purple twist-on type.Require a torque screwdriver to use properly.Just not happy with the price of these. Keeps going up up up

Aluminum wiring. Worked well to splice a line down to my tv. House is still standing.

I have not used the latest ones I purchased but the same ones in the past are excellent for the electrical connection. The big thing is the safety to prevent an electrical short. Rather pricey and need a special screwdriver to put them in but yes I really think they are the only way to help with aluminum to copper wire. I consider them as a fire preventative.
