ADKS cables are rated at 5 watt per feet, 120 Vac and have a three wire grounded plug with a 6 feet/2-meter power cord. Roof and gutter de-icing kits include the appropriate number of roof clips and cable spacers. ADKS cables are UL listed to Canadian Safety Standards and CSA Certified. This cable provides an uninterrupted path for melting water, adapting to most roof and gutter configurations.
