I'm currently using these with 16 AWG wire. At first I thought they didn't fit properly because the screw wouldn't tighten far enough to hold the wire in - turns out stripping a bit more wire and bending it over onto itself fills the gap and makes the screw tighten down on the wire properly. I really like that the wire can come in from the base or the side since, depending on the situation, one of the options tends to work better.

The weight of these things assured me without even removing them from their package that they were great quality. Once you get the hang of putting your speaker cables in them you'll want to put them everywhere! Threading speaker wires thru your speaker posts is so archaic.Once you try banana plugs you won't go back! Thank you! Awesome price too!

High quality, easy to use, snug fit to terminals. Definitely recommend!

they are easy to use and have a great connection

As described, high quality and fast delivery.

Price has gone up over time, but still great quality, no concerns running my hifi system with these
