General Wire Drain Cables are made from heavy-gauge wire coiled tightly around 49-strand aircraft-type wire rope and heat treated. These cables have unequalled strength and the right amount of flexibility. These cables are so tough, they carries a one-year warranty against defect or breakage. Make sure to protect your drain cables with snake oil. Snake Oil preserves and protects your sewer cables against rust and corrosion. It's better than common lubricants because its special rust inhibitor cuts through moisture and replaces it with a rust resistant coating.
