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.

Easy to install:

  1. Unscrew the casing to reveal the inner barrel.
  2. Loosen the two small screws to make room for your speaker wire.
  3. Slide the casing down the speaker wire before terminating the wire to the inner barrel.
  4. Feed the speaker wire into the inner barrel of the banana plug.
  5. Tighten the screws to secure the speaker wire.
  6. Screw the outer casing back over the inner barrel.

The Right Angle connectors provide a cleaner install while reducing strain on cables and on the speaker wire terminals.

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.

Great Product Good Value

There is a video on the Sewell website showing weights being hung off of a Silverback Banana Plug. Seems like over engineering, but after installing them I have no doubt they will never come loose on their own. Attractive product that is well engineered, manufactured and packaged. I ran into the Sewell brand on the PS Audio website when it noted Sewell speaker cables were included with one of their systems. They take audio quality pretty seriously, so I assumed Sewell must make high quality connections if they met their standards. It’s hard to find quality these days even when you pay for it. These banana plugs are excellent and I am very pleased to have found them before I ordered some generic ones.

Did not work

Tiny flat head screws do not tighten all the way down. This prevents you from getting the sleeve in place. The screw should be an Allen key or torx head in order to fully tighten. I am using 12 AWG and cannot get them to tighten all the way.

I'm sorry you had a negative experience with our product! Please feel free to reach out to our customer service or tech support team!
