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:

  1. Unscrew the jacket to reveal the core of the Silverback Banana Plug.
  2. Loosen the two small screws to accomodate the size of your speaker wire.
  3. Feed the speaker wire into the core of the banana plug.
  4. Tighten the screws to secure the speaker wire.
  5. Replace the jacket over the core.

Premium Materials

  • 24K Gold plating
  • Solid brass banana plug tip and housing
  • Aluminium outer sleeve (with brass threaded insert)
  • Non-conductive clear coating on the aluminum sleeves
  • Mini Screwdriver included on the 6 and 12-packs

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.

Silverback banana plugs

Banana plugs are an excellent replacement for bare wires, and these are excellent banana plugs.

Silverback Banana Plugs

Silverback Banana Plugs are well designed and easy to use. They provide a straight connection that is in-line with the source wire rather that at right angles which makes the connection panel neater and more positive. The double screw clamping design assures a very tight electrical connection. They are excellent.

Great little termination

I like the double screws; little screw driver is included - nice touch. Sleek, well-built, effective.

Have not received order yet

Package has been sitting at USPS Santa Clara since 8 Dec. Once I receive them, I will be happy to provide feedback.


High Quality speaker wire and connectors that I am enjoying fully. My stereo system sounds open and unrestrained!
