High-conductivity copper construction: ring lugs are made from premium copper for low electrical resistance, reliable current flow, and reduced voltage drop in critical connections. Improved temperature durability: the ring terminal design and materials resist heat and maintain contact integrity under higher operating temperatures, lowering the risk of failure from thermal stress. Open-wire crimp for faster, more reliable terminations: the open-wire crimp is easier to position, crimp and solder than standard closed-sleeve types, simplifying installation and producing a solid mechanical and electrical bond. Broad cable compatibility: designed to work well with any cable, the open crimp accepts common conductor sizes and types, making these lugs versatile across installations. Function and fit: ring lug terminals provide a secure stud or screw mounting for permanent or serviceable electrical connections, ideal where a stable, low-resistance contact is required. Durable performance: the combination of copper material and robust crimp design offers long-term reliability in repeated-use or vibration-prone environments. Typical applications Automotive and powersports battery connections: create dependable, low-resistance links to battery posts and starter circuits. Electrical panels and grounding: attach conductors to grounding bars, bus bars, or panel studs for secure service connections. Industrial and marine equipment: use where heat, vibration, and long-term contact integrity matter. What you get A simple, professionally performing ring terminal that makes installations faster and more reliable by combining high-conductivity copper with an easy-to-use open-wire crimp design.
