They could do one better.I use Wago lever nuts for almost everything, love that they made a smaller version as that was my only ever complaint about them :thumbsup:
They don't have a 4 port, you have to use a 5 port if you only spice 4 wires. That's not that big of a deal, but sometimes the 5 port is too big for those old metal boxes.
So I think they should make a 4 port, but instead of having it longways like the 5 port, they should have it over and under. Like this:
Two levers would stick out on each side. It would be about the size of a normal wirenut, and the square configuration would fit better IMO.
