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.

Great customer service!
Very easy to use, perfect for my application.
They are banana plugs and they work. Would have been helpful to have a small instruction with the package on how they come apart to use.
The order was shipped quickly and I received within a week. There was a defect in one of the Plugs. The replacement was shipped quickly. I am appreciative of Sewell’s Customer Service.
I’ve been buying these banana plugs for many years as I expand my home theater system. I bought some in May of last and needed some warranty help as a couple of the plugs were defective, even though I was out of warranty period, they still provided me some replacements. Bonus that the 12 gauge ones work with 10 gauge wires as well
