StreetWires 1/0-gauge Inter-Lok® Power Rings® provide a highly-secure, compression fit connection in which every strand of your power wire maintains gas-tight contact with the terminal. Just insert the bare wire end and twist the Inter-Lok terminal to hold the wire in place.

Unlike crimp-on rings, Inter-Lok® rings are reusable. They are precision machined from high-conductivity brass with an attractive, corrosion-resistant Diamond Plate Nickel plating. Machined external sculpting adds flair to your installation. Lifetime warranty.
