24K Gold Contacts: Monster Cable's Black Platinum QuickLock Banana-plug connectors utilize 24k gold contacts for mast signal transfer and corrosion resistance.

Gripping Teeth & Ring Lock: The Black Platinum QuickLock Banana-plug connectors employ gripping teeth and a ring-lock for a secure connection to your speaker wire that will not turn lose.

Self-Crimping Installation: Unlike most connectors that require crimping tools, these QuickLock connectors from Monster Cable require no tools.

  • Strip the cable jacket to expose 5/8" of copper stranding.
  • Using your fingers, twist the copper strands to form a point.
  • Slip the QuickLock mounting post over the exposed copper.
  • Fan the copper strands over the connector base.
  • Place the connector over the copper strands, turning it clockwise onto the threaded portion of the mounting post until secure.

I had a Denon amp once that had back plane connectors that worked like these plugs are described. I am in the process of restoring a Carver legacy system using some DIY speakers that are nearing completion. Now I have some plugs coming that I am sure will be a pleasure to use. [ George  Jan 23, 2018 ]
Previous product purchase and good quality. [ Chuck  Sep 16, 2017 ]
Over the past few years, I have slowly added these connectors at speaker and receiver terminals. Usually timed when I had cause to disconnect a component. It makes reconnecting things and future disconnects much easier. I have had good experience with monster products in the past. [ Winfield  Jul 14, 2017 ]
Was advised that these were the connectors for the speakers and the receiver. [ Dory  Jul 14, 2017 ]

2 questions already asked

Thinking back to when I connected mine, I believe they will accommodate a second wire. It will be tight, though. [ Joseph  Jun 01, 2018 ]
I doubt it. I'm using 14 gauge wiring and they fit in easily enough for one wire, but two would be a biy too thick in my opinion. On the other hand, you're only out about $25 if you try it and it doesn't work. [ Donald  Jun 01, 2018 ]
I used a 16 gauge wire/cable and, after twisting the wire tightly, it easily slipped into the opening. I don't think it will accommodate two 14 gauge wires twisted together. But, frankly, I'm not sure. Suggest you call or email a "technical type" before purchasing. [ Cynthia  May 29, 2018 ]
I'm afraid Monster doesn't specify any maximum cable gauge for their self-crimping Banana connectors. You may want to try reaching out to their support directly by phone at 877-800-8989. [ Larry  Aug 06, 2017 ]  Staff
I'm using 16 gauge speaker wire and there's additional space available in connector; but I'm not sure if enough for 10 gauge. Sorry I can't help. [ Cynthia  Aug 01, 2017 ]
