2-Port AlumiConn AL/CU Connector-10 Pack

I have been an electrician for 35 years. These connectors by King are by far the safest and easiest to install on aluminum wiring. For pig tailing outlets use the 3 port model. I hope sellers will lower the price some. Most people affected by aluminum wire hazards are low income or disabled.

If you live in an older house with aluminum wiring like mine, any wiring job requires AL/CU connectors when doing aluminum to copper connections. It is pricey for what they are but theyre easy to use and hold the cables good. I'd definitely recommend over twist nuts

We just bought a house built in the 70s with aluminum wiring. As we update switches, lights, ceiling fans, etc., these have worked very well to secure a connection between Al and Cu wire. We have open circuits where old wire nuts, even ones that were supposed to be for Al-Cu connections, have come loose due to Aluminum expanding. To do that, they would have had to heat up, and that's the fire danger, along with the electric arc that gap could cause. The set screws easily clamp down hard so these leads are not going anywhere. They are close enough to the size of the wire nuts they replace to not crowd the box as we switch over. If you have to connect aluminum wire to copper, use these! Also come in three lead style.

I really like these. I've dealt with numerous aluminum wiring issues at my house over the years. There are problems finding the right receptacle's for aluminum wire now so this is perfect, it lets me fix my issue with new readily available parts with the use of pigtails from my old wiring. Very happy.

I've used these for several wiring projects at my house and highly recommend them. They are simple to use and provide a peace of mind knowing they reduce the risk of fire. The major draw backs on these are the price and the size. Averaging $3+ per connector, it gets pretty pricey replacing outlets, switches and fixture. Also, your gang box will become pretty crowed, especially if you're using dimmer switches. I typically use the 3 port connectors, but the 2 port have been handy for multiple things; just buy the right ones based on you project. Although you can use these with a standard screwdriver, I recommend getting a torque if you will be using these in any volume.

This is the permanent fix for any aluminum wiring issues. Insurance company recommended it.

Work great but are absurdly expensive. Must be a huuugggeee profit margin on these babies.

Great product. Easy to use (if you also get a torque screwdriver). Very useful to have these 2 port connectors in some places where 3 port connectors are not needed.
