Road Power Extra Heavy-Duty Booster Cable features Polar-Glo clamps and T-Prene jacket insulation, designed to deliver exceptional safety and reliability even in the most extreme weather conditions. The ergonomically designed Polar-Glo clamps attach securely to both top and side post batteries, making them easy to handle for everyone. These clamps include triple-polarity identification with color coding, intent stamping, and glow-in-the-dark labels for added convenience and safety. Energized clamp surfaces are shielded to prevent short circuits, and all conductive surfaces are recessed to avoid accidental contact. The T-Prene insulation remains flexible in severe temperatures and resists oil, chemicals, and water. Constructed with heavy-duty 4-gauge wire, this booster cable performs effectively with cars, trucks, and SU alike. It is UL listed, comes in a 16-foot length, and is packaged in a retail-style box for easy display. Model Number: 08666-01-04
