Scotchlok Moisture Guard Weatherproof, UV-Resistant Connector for 2-3 Wires, 16-14 AWG (solid/stranded), 25 per bag

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.

Best product available for landscape light wiring. Does the job right the first time. It will take effort to snap closed (I used a rubber mallet and small board - not enough strength in my hands to squeeze and the tool made especially for these is too $$$). Note that no stripping is required! Plan to waste a few trying getting the hang of it and double check before you close them - not really made for reuse.

Worked great for fixing some underground low voltage landscape wire for my lights Update! So I've used a few more of these and figured out a little trick, most of the led landscape lights have super thin wires, (22g or so) had a couple of tough ones to actually make the splice / connection inside, so what I do now is strip the lights wires and weave / twist in an additional striped 16-18g wire (just the ends obviously). Then feed BOTH wires into the centre hole and once I get in I cut the sacrificial 18g wire so that it ends just inside the connectors rubber seal. Makes a solid connection and had ZERO problems with them since!

I tried 4 different connectors for landscape lights. What a nightmare the other ones were. These are FANTASTIC. Highly recommended. It almost makes adding connectors fun! They are worth every cent that they cost. TIP: The holes you push the wires through are VERY tight (which you WANT). What I did was cut the wires at an angle. It made it much easier to insert and the angled portion goes all the way to the end and isn't involved in the electrical connection that's made when crimping. I used 14 AWG stranded wire. I haven't tried 12 AWG wire yet.

Easy to use and great for landscape lighting connections
