This 12 gauge extension cord will protect your tools by providing the right amount of power that is needed when using on an extension cord. The Pro Star series cords have become the industry standard for durability and safety. These cords are molded with large strain reliefs that prevent the ends from pulling away from the body. Century Wire uses only soft-drawn, bunch stranded 100% copper conductors for maximum flexibility and are manufactured with cold weather insulating and jacketing compounds. As a result, Pro Star cords are extra flexible in temperatures well below freezing.
