Heavy duty cable lug designed to fit solid or stranded wire Wire can be crimped or soldered to copper lug Closed end design to keep environmental conditions (e.g. outdoor environment) away from the cable connection Meets standard 486 for WIRE CONNECTORS AND SOLDERING LUGS Manufactured from pure annealed ASTM-B-152 copper with excellent conductivity characteristics WNI pure copper cable lugs are heavy duty, pure copper, electrical connectors designed for high amperage applications. They are an excellent choice for making connections in battery banks, back-up power set-ups, battery to inverter connections, car and audio system wiring, general battery wiring (for golf-carts, RV’s, boats, engines, winches, etc), and any other electrical connection that requires a heavy-duty high amperage connection.
