Step 1:  Carefully strip the ends of your speaker wire to expose about 1.5 cm (⅝”) of bare wire.

Step 2: Twist the exposed strands of wire tightly, so that there are no loose strands.

Step 3: Remove the red or black outer alloy jacket from a banana plug by holding the exposed gold end, and gently unscrewing the outer jacket.

Step 4: Use a small flat-head screwdriver to partially loosen the small gold set screws from the exposed gold tube.  Try not to remove them entirely, as they can be fiddly to re-insert.  You're wanting to open a channel down the center of the gold tube.

Step 5: Insert the stripped speaker wire fully into the gold tube.

Step 6: Use the flat head screwdriver to tighten the set screws so that they firmly grip the inserted speaker wire.

Step 7: Holding the attached banana plug in one hand, and the speaker wire in the other, give a tug on the speaker wire, to make sure it will not easily pull out of the gold tube.  If it stays firmly in place, proceed to step 8 below.  If the wire pulls out of the tube, please repeat from Step 4 above, and review our FAQ below.

Step 8: Reinstall the outer coloured alloy jacket on your banana plug.  Make sure to match the jacket colour to the polarity of the connection.  Red jacket matches positive polarity.  Black jacket matches negative polarity.


Here are a few common questions from some of our customers, along with our answers to them.  If you have any questions or concerns about this FAQ or the following instructions, please feel free to reach out to us, we’d be happy to help.

Question: My speaker bindings don’t seem to have a receptacle that will accommodate the banana plugs?

Answer: Many speakers, particularly those built or designed in Europe, ship with plastic caps covering the receptacles in their binding posts.  These are usually made of black or red plastic, and can be gently pried out of the top of the binding post with a small flat head screwdriver.  

Question: Why can’t I fit these plugs into the binding posts on my speakers or amplifier?  They seem to be too large to fit?

Answer: Our banana plugs will fit the vast majority (99%+) of standard binding posts.  Once installed correctly on your speaker wire (see below) you just need to line the plug up carefully, and push it solidly into the receptacle at the top of the binding.  This can take a bit of force, particularly with brand new plugs.  A snug fit is good, as it means a great connection.

Question: When I plug my speaker wires into the binding posts, they wobble around more than I expected?

Answer: Please make sure that the plastic nut on your binding post is fully tightened down to the base of the bindings before plugging in your speaker wires.  If the nut is loose, it will prevent the banana plug from sitting fully in the receptacle.

Question: My speaker wire is very thin, and the set screws don’t seem to be gripping it tightly?

Answer: Just strip the shielding on your wire back a little bit further, double the bare wire back over itself and apply a little twist to the doubled portion of the wire.  This will provide a larger diameter of wire for the set screws to grip.

Question: My speaker wire is very thick, and I’m having a hard time inserting it into the banana plug?

Answer: Our banana plugs have been used extensively with 11 AWG speaker wire, and narrower gauges.  Please try putting a tight twist on the stripped portion of the wire, to tighten the strands together before inserting.

Question: The outer jacket of my banana plugs seems to loosen over time, is there anything I can do to prevent this?

Answer: for most customers, who will be installing these plugs on their speaker wires and then plugging the wires into their system, the outer jackets will remain screwed into place without further steps.  

For customers who frequently unplug and re-insert their banana plugs (between different speakers or components, as we frequently do ourselves) it is possible to add a very small drop of Loctite 222 Purple Low strength Threadlocker to the gold thread pattern on the middle of the banana plug.  Then screw on the outer colour-coded jacket tightly, and allow to set for about 20 minutes.  This will prevent the outer jacket from loosening gradually over time through regular use. **Note 1: make sure you have correctly installed your banana plug on your speaker wire before using the purple threadlocker.  **Note 2: please don’t use the stronger bonding blue or red Threadlocker options, as they will make it difficult or impossible to repurpose your banana plugs in the future, should you wish to do so.
