Performance Plus Wire Connector R/Y+JUG, Red/Yellow, Flexible Steel Spring Connectors, Copper, CSA Certified, UL Listed, Jug of 500, 22-8 AWG

These are great and a good value.

These are some of the best wire connectors I have used in 50 years of wiring. A bit large but great to handle both 2-5 (depending on gauge) wires so easily. My go to unless the box is really crowded.

This wire nut is the best wire nut to carry on a van with limited space , can be used on a wide range of wire gauge.

I'm a master electrician, and a owner of a electrical contracting company. The 3M nuts are the only ones we use on every single jobsite. I love the feel of them, and they hook in perfectly every single time. Yes they are a little larger than your cheap-o nuts, but the labor cost savings is more than enough to offset the cost of a deep box or a 4 11/16. I won't use anything else!

If you know you know. There’s a good reason why these 3M wire nuts are more expensive than others. Definitely my favorite style of wire nut. With over 20 years experience as an electrician I’m convinced they are top of the line.

Uou can use these instead of blues on the larger wire sizes I like the blue orange ones cause you can fit 3 # 12's in them and not fill up the box. easy on the fingers.

This 3M product is well worth the extra money spent over the common rigid plastic wire nuts commonly sold in most home supply stores. The soft pliable shoulders make it far easier to tuck into electrical boxes than the cheaper wire nuts that have flooded the market.

Always get a good bite on the wires and love the extra rubber skirt on the bottom for that little bit extra protection.
