3M Scotchlok Moisture Guard Connector, 100 per jug

They worked flawlessly for my landscape lighting project using 12/2 wire and 16 GA fixtures. I was able to tie into the existing 10/2 wire IF I stripped the wire and ideally first removing the 3 hole gasket. As others mentioned, I found channellocks work best .. and you'll probably ruin 2-3 getting use to these connectors. The trick is twisting and not compressing and don't lube the wires .. you need a strong grip. I'd also recommend having a rag handy because you will get the gel on both the channel locks and your fingers. When you need to use just 2 wires .. don't worry and don't put a blank cut wire as a cap it will only act as a wick to the water, there's plenty of gel to fill the blank.I'd love it if there was a triple 12/2 connector for the T branches.

These are the only way to go for landscape lighting. Took me a couple of wasted connectors to get the hang of crimping the connectors, but great otherwise.

Great product. Use these all the time. Easy to install.

Awesome product. Used to wire trailer brakes.
