Robust Lever Wire Kit: Quick Connect Electrical Splicing, Compact Conductor 28-12 AWG for Reliable Inline Circuits (LT933, 10)

These wire joiners are great and work very well, wire do not pull out easy from the joiner

When you are trying to connect power lines in a small switch box, these work great for bringing in one power line (esp 12 gauge) and splitting it in two directions. Fits into tight space and organizes crowded wires.

Very effective and useful.

I have use many types of these in home Christmas lighting projects. These ones are shorter in length than most, which has pros and cons. Pro is they take up less space and are less obtrusive and weigh less. Cons are there are no test ports on top to insert voltage probes, are very useful feature on other models. Another con is the length of wire inserted is shorter, may have less contact with the spring terminal but I haven't had a problem with wires pulling out. Lever action is a little stiff but ok for occasional use.

Easy to use. Holds tight. I used them in a tight space were wire nuts would have been aa pain. They do take up more space then wire nuts.

Work very well. Better thsn butt splicers.

Used these for splitting a signal to multiple fireworks on one q. They are wonderful.

Good choice for connecting lines that may need to be disconnected.
