NEW – (30 Feet) 18 AWG SOOW 3/C Cord 600 Volt Water Resistant UL (C)UL VW-1 Heavy Duty Electrical Cord. VW-1 is a vertical flame rating that measures the resistance of insulating materials to the propagation of a fire. The test involves mounting lengths of wire vertically in a ventilated chamber and attempting to ignite the wire with a gas flame. Through a series of 15 second direct burn intervals, the sample wire must self-extinguish within a measured time to achieve VW-1 status. SOOW cord resists oil, solvents, water, ozone, aging, and abrasion. It is also flame retardant, flexible, and durable. The 'W' means the cable is weather and water-resistant. These cables are very high quality and I guarantee you’ll be satisfied or return them for a free full refund. You can’t go wrong at $1.00 per foot. Free Same Day Shipping!
