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

I bought these for a low voltage landscape lighting installation. The main trunk line was #12/2 and the fixture wires were #16/2. I had no confidence in the supplied insulation piercing connectors attached to the end of the fixture pigtails [ from a home center starting with the letter L ] so I cut them off and used these. 3M has been making products like this for years for the telephone utility market, these are just bigger. The outer ports will accept up to #12 AWG wire, but if you're using low voltage landscape wire, you will need to open up the insert holes (grey cap on one end) to accept the larger insulation diameter. I used a center punch. The bottom side, which you can't see in this photo, is clear plastic so you can make sure the wires are fully inserted BEFORE you squeeze. Use a pair of Chanellocks to make sure the connector is fully closed. You will probably want to wear disposable gloves and have some paper towels nearby as the silicone gel filling will ooze out when you squeeze the connector. This gel is both an insulator and a water repellent. These connectors are rated for direct burial at voltage up to 150V.

Excellent product, for those having hard time to introduce the wires in the connector, use a mail or a pointy tool, then put it into the holes and use the silicone from inside to lubricate the introduction of the wires, I did it with out a problem.

This Connector works very well once I figured out how to use it.I noticed that other users also had difficulty in inserting the wires into the connector.After struggling with the same issue on the first few wires, I sharpened each wire like a pencil with a utility knife and insertion was very easy.Yes, you need Channel Lock Pliers to Crimp it down all the way and make good connections.I also agree the Waterproof Gel does ooze out and make a mess.But, that is confirmation that you crimped the wires !

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.

Bought these to rewire a goose neck trailer and am beyond disappointed. I got these because i could combine 3 wires and it be weather proof. I anticipated it cutting into the wire and holding with a clamp style feature but it does not. You clamp it down and it looks good but if there is any pressure pulling on the wire at all it pulls right out. The only thing gripping on the wire is the metal cutter that should connect all the wires to electrify them. I hope it will last the summer but will need to pull it in next winter and rewire it all again. Made more work than if I would have just spent the time to use heat shrink butt connectors.

I am using these with landscape lighting's 12 AWG cord. Most is direct burial so these connectors work very well. They have three wire ports, 2 for the in/out of the 12 AWG and the third, 16 AWG, for the light being installed. Lots of gel to protect the connection and no wire prep is needed. Just cut the wire, insert into connector, and clamp the connector to make connection and snap the top and bottom parts together

Very subtle - these do not accommodate three 16 AWG wires as the ad title states, only two. Small detail, the outside two wire holes can take 16-14 AWG, but the center only takes 20-18 AWG. They are great waterproof connectors, but too much to pay if they can only take two of the larger wires.

This product has provided to be moisture resistant. I have installed many of these connectors and they have been reliable.
