Durable insulation and pure copper not that cca bs
Size: 1/0 Gauge 5FT
Good quality. Solid copper, not that cca bs. Stiff and durable insulation. Used for big 3 car audio grounds on high output alternator. Great results. Will mention that it’s not as thick as some other brands but not by much. Terminals still crimped tightly with 1/0 gauge
