Our most secure banana plugs
Silverback banana plugs have the quality you’ve come to expect from Sewell, including gold plated connectors and a heavy-duty casing. What sets these banana plugs apart is the unique dual-screw lock design. This connection will secure your cable more than a single-screw or open-screw design. Dual-screw connectivity provides a secure connection, durability, and a clear signal transmission through the added contact. Silverback Banana Plugs accommodate up to 10 AWG speaker wire.
How to Install Silverback Banana Plugs:
- Unscrew the jacket to reveal the core of the Silverback Banana Plug.
- Loosen the two small screws to accomodate the size of your speaker wire.
- Feed the speaker wire into the core of the banana plug.
- Tighten the screws to secure the speaker wire.
- Replace the jacket over the core.

Why Banana Plugs?
This banana plug interface is found on audio/video receivers, speaker wall plates, and more. Banana plugs offer an alternative to inserting a bare speaker wire into your equipment. Bare wire connections tend to get pulled out or frizzy after time passes, are prone to corrosion, and are a hassle to insert onto the equipment. Banana plugs offer a quick and secure connection that is both reliable and makes future changes painless.

Awesome
Placed order for these and other equipment on the 16th the other items shipped almost immediately however by the 29th these still had not, reached out to support and they responded within a couple hours apologized and overnighted me replacements. Quite happy with the customer service.
So far I have been very pleased with them, the seem well made are easy to setup, make a solid connection. There is only one problem. On a couple of them the set screws were screwed all the way in on arrival to the point that they had gone past the threads in the connectors and where crooked inside the plug. I was able to work them out with some effort, the plugs and screws were undamaged but it took some work to get the screws out. I suspect they moved due to vibration in shipping. If it were not for that would be 5/5
I needed the plugs on time and instead was stressed to the max by them being sent to a wrong address when my address is the ONLY address in my profile! I also wonder why I am (no doubt) paying for a screwdriver with every shipment? I have my own professional screwdrivers, and I am forced to throw out at least one supplied screwdriver with every shipment. Time to look at other suppliers methinks!
I have two bad connectors and I can't seem to raise anyone to help me get replacements.
Long and dedicated group. Remembers what got them to the dance.
