Product Description The Road Power Medium Duty Booster Cables are suited for all vehicle typs including full sized trucks, vans, SUVs, and commercial equipment. Our premium jacket is water and chemical resistant and remains flexible up to -50F. These cables are 12 feet, 8 gauge and come with a limited lifetime warranty. From the Manufacturer Road Power medium-duty booster cables feature dual-extruded wire to provide the user with easy, tangle-free operation. Cables are manufactured with either a PVC or T-Prene jacket. While both jackets perform well in warm or cold climates, T-Prene provides additional oil, chemical, and water resistance. Medium-duty booster cables come standard with 400-Amp copper-plated steel clamps but can easily be upgraded to Polar-Glo clamps. The Polar-Glo clamps triple-polarity identification includes color-coding, indent stamping, and glow-in-the-dark labels. To ensure the highest levels of user-safety, all energized Polar-Glo clamp surfaces are shielded to avoid short circuits and all conductive clamp surfaces are recessed to prevent accidental contact.
