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


    My order was small and when I started looking online other vendors were wanting more for shipping than the price of the items. Then I checked Sewell Direct and they had what I wanted at a higher price but the FREE SHIPPING more than compensated for that. My order arrived very quickly in a re-usable mailer which is a nice touch. In the end, I believe I purchased a higher quality product at a lower total cost than other sellers could provide. When I need things in the future, if Sewell sells them, that's where I'll look first.
