BlueRigger Premium 4mm 24k Gold Plated Enclosed Screw Type Banana/Speaker Plugs for Speaker Wire for Amplifier (6 Pair / 12 Pcs)

Good quality banana plugs.

Simple installation with my Leatherman or small screwdriver.

Works!!

For secondary systems these work well. If the plating holds up over time, they can end up being quite good value. Most generic Chinese 'products' are polished brass and become black with time. These have no strain relief apart from the second set screw, so you need to make sure you don't strip the wire down too much. The spring action is very firm when new so they are quite a snug fit. Some sockets are exactly 4mm and the compression fit is quite tough at first. Don't use these right away if you plan on making changes or moving stuff around. The springiness will reduce over time, so there's that.

There is nothing to dislike about this item. It's easy to use good cable clamping quality's, very durable and well made. Recommended 100%.
