Our heavy duty Pro Power extension cords have become the industry standard for durability and safety. We use only soft-drawn,
bunch stranded 100% copper conductors for maximum flexibility. In addition, our heavy duty plugs are molded with large strain
reliefs that prevent the ends from pulling away from the body. Our cords are manufactured with cold weather insulating and jacketing
cord compounds. As a result, Pro Power cords are extra flexible in temperatures well below freezing.
