Works great with all speaker wires
Size: 6 pairs
It works pretty well with standard and thin speaker wires. It makes so much easier to plug and unplug speaker wires. Color coded makes it easier for future. Banana plugs are worth. Double screws ensure wires remain securely attached. Screws are bit too tiny and had to run to the store to get one of those fine tip screw driver though.

Great Quality and Value - Perfect Connections
Size: 10 Pairs, Pattern Name: Banana Plugs
I used these Monoprice 24k gold-plated banana plugs to connect both my surround sound and desktop speakers, and they work perfectly. The connections are solid and secure, with no looseness or signal issues.
They’re easy to install, look great, and offer excellent value for the price. Highly recommended!

Fantastic speaker plug at a great price!
Size: 5 Pack, Pattern Name: Banana Plugs
This is a product that gets the job done effectively, and at a good price. Banana plugs are used to clean up speaker wire - you can generally screw in speaker wire, but banana plugs provide a nice interface that allows you to plug in and remove speaker wire as needed.
These closed plugs do a good job terminating / hiding the wire. They fit very well into various components and amps that I own.
INSTRUCTIONS to install / use them:
* Remove around 1" - 2" of the white casing to expose the red and white individual speaker wires
* Strip each wire so ~1/2" metal is showing
* Make sure the plug end is screwed in tightly (this does not need to come out)
* Unscrew the base of the plug from the other end
* WithOUT twisting the metal wiring, insert the wire (match wire color with plug color; start with either one) from the bottom of the plug until the metal sticks out the top
* Have ~1/4" metal hanging past the plug
* take the wiring and drape it down the sides of the plug (just the smooth side, do NOT cover any of the screw threading or it will be very hard to close it)
* Spread the draped wiring around the plug as evenly as possible (makes it easier to screw in later)
* Screw the two ends of the plug back together (the side with the draped wiring will go inside the plug)
* If you get stuck while screwing it back in, unscrew and adjust the wiring
* Repeat for the other side, and you're done!
