About the Metra ethereal Self-crimping Banana Connectors

These heavy-duty banana connectors feature a two-piece, screw-on design that gives you easy and reliable speaker cable termination — with no tools needed. 24k gold-plated contacts ensure maximum signal transfer without corrosion. If your receiver or speakers have banana-compatible binding posts, these connectors are super-easy to plug in. We find banana connectors especially handy for the space-challenged rear panels of A/V receivers.

  • works with speaker wire up to 10-gauge
  • 24k gold-plated contacts for corrosion resistance
  • easy screw-on design — no tools required
  • warranty: limited lifetime
  • Our 60-day money-back guarantee
  • MFR # CS-BAN3

Customer Q&A

1 question already asked

Could someone provide the length of the casing on these? I bought some On-Q banana plugs to use with Polk speakers, but they are too long to fit into the depression in the back of the speaker where the connections sit. These look shorter, but I can't find a length in the specs.

The self cramping area is 5/8" of an inch - not aware of shorter versions. Hope this helps.

It's about 23/32 of an age; just shy of 3/4 of an inch.
[ Murray  Jul 02, 2018 ]
The entire piece in gold is 1 inch
