How to Install Deadbolt Banana Plugs

  1. Unscrew the cap off the Deadbolt Banana Plug.
  2. Feed the bare conductor of the speaker wire through the center hole of the banana plug. (strip wire about 1/2")
  3. Bend the wires of the speaker wire down around the teeth.
  4. Replace the cap to secure the speaker wire.
  5. Your Deadbolt Banana Plug is ready for connection.

What Are Banana Plugs?

Many electronics use the banana plug interface, also known as binding post (referring to this connection in its female form). This female binding post connection that accepts this banana plug is found on virtually all audio/video receivers, speaker wall plates, and more.

Banana plugs offer an alternative to inserting a bare speaker wire into the equipment. Often a bare speaker connection is not as reliable as a guaranteed banana plug connection. Wires tend to get pulled out or frizzy after time passes. Banana plugs require only one install, giving you a permanent and robust connector at the end of your speaker wire.

High quality; brilliant design

These banana plugs are extremely high quality and brilliantly designed. They securely terminate one (or more) speaker wires in such a way that, once fastened, they will never come loose. Since the wire(s) enter the back of the plug, an extremely clean, organized and accessible array of speaker wires at the back of the amplifier is assured. I recommend these plugs w/o reservation.

deadlocks your connections

I chose these banana plugs four two reasons. First and foremost reason was the design,with its jaws it makes a broader and more solid connection. the second reason was the shortness of the plugs which allows ability to fit in spots with tight depth issues. I had never heard of Sewell previously, but have been spreading the word about the product line,quality,reasonable prices, and timely delivery of Sewell Direct. Do yourself a favor and check them out, you will be glad you did!!

Great customer service

In my first review I mentioned that one out of 24 plugs was defective and Sewell unsolicited contacted me and said they were sending a replacement,you can't beat that for customer service

Sorry to hear that you got a bad plug. Let me know your order number and I'll get a replacement sent out.
