WAGO 221 Lever-Nuts 36pc Compact Splicing Wire Connector Assortment. Includes (16x) 221-412, (12x) 221-413, (8X) 221-415

Great concept/product. I will never use wire nuts again. More expensive but saves time.

This has to be the single best timesaver EVER when it comes to electrical wiring. I used these to re-wire a car trailer, as well as my shed…12V to 120V, covers everything! These things rock! Pay attention though, only the WAGO brand is actually “UL listed“… While you may not be subject to inspection with any of your work, I highly recommend spending the extra money for this level of quality to CYA!!

Liked the simple install. Disliked it made me second guess because it seems like a loose connection. But happy overall.

Allows for easier later additions to the boxes...easy to tap in future line extensions.

Yes, they are more expensive than wire nuts, but far easier to install. And if you need to disconnect or add a wire, very easy compared to undoing a twisted group of wire nutted wires. The cam lock is strong and snaps the wire securely. Plenty of extreme test videos out there showing the connectors can go well beyond whats needed both from a current safety and pull-out perspective. I wrap electrical tape around the wires and head when done, just like I have done with wire nuts.

Great product

So easy to use with no guess work of connection. I just installed 7 outlets in my basement and these made it all easier.

Forget twisting, compressing, and clipping. Far less time on the ladder installing light fixtures

Saw these on a video and decided to try them. Great connectors and seem to hold well. I believe these would be much safer to use then basic twist on wire connectors. It appears to cover the wires perfectly (if cut properly) so maybe less chance of arcing and they take up less space as well.

Used these on a retro fit wiring job of ceiling Make connecting short house wires a breeze ! Only have one complaint, no 4 wire connectors ! Why, apparently this company doesn’t offer this options.
