Making the best connection
The last thing you want to run into when making a power cable connection at the battery is a loose connection which is not only dangerous but there is a loss in voltage potential. Harmony Audio offers high quality ring terminals that feature a substantial set screw that securely tightens the power cable to the terminal ensuring an excellent connection. The ring is 5/16" in diameter which is commonly found on factory and aftermarket batteries along with other bolt points on most vehicles. The ring terminal can be used for either a positive or negative battery connection and features a nickel plated finish that looks great and offers the maximum current transfer.

Highlights:

  • 1/0 Gauge Ring Terminal
  • Nickel Plated Finish
  • Ideal for Power or Ground Cable
  • 5/16" Hole Diameter
  • Set Screw ensures Tight Connection
  • Ultra Conductive
