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

Goodbye twist-on wire nuts, forever! WAGO lever nuts make positive, strong electrical wire connections and take up very little space in junction boxes. Can be used with both solid and stranded wires. YT has videos of their use. I love them! Inspired invention! Thank you WAGO!

I love these connectors. I am a handyman and this saves time and makes connections secure and solid. There is some talk about the levers opening while closing a box or pushing in a outlet or switch. Easy solution, which I do anyway, WRAP THEM IN ELECTRICAL TAPE. Solved. Watch YouTube videos about them, you will love them too.

Electrical wiring for the house. I will find many other uses for them also.

While installing a bathroom exhaust fan using the lever nuts, I locked each one onto the appropriate wire on my bench, then just made the last connections up in the unit, with no worries of dropping the wire nuts or putting them in wrong.

Excellent, if a bit pricey. Honestly, for virtually all wiring connection needs, these effectively replace wire nuts.

Easy to use

Work better than I expected. Easiest way to splice and the added advantage of the ability to undo. I am sure I am not the first person that wished you could undue a splice. Where has this product been? I could have used this hundreds of times. I bought the small pack to test. I will be purchasing more, say goodbye to the crimped splices. It works so well, I couldnt believe it.

These may be little but they are a well designed and amazing product. They are strong and reliable.

This is a really great update on an old product. It is very easy to use; very economical; well packaged; very good quality; provides a lot of variable items for different situation, and makes wiring easy to use. Also if you make a mistake, it is easy to back out of the mistake and try again.

I expected this product to change my mind on electrical work in the house cause I just dislike electrical work all together . With that being said changed my mind completely on doing electrical work with the ease of use of these glorious things
