Gutter Melt SR 120, 208, 240, and 277V Self Regulating roof and gutter heat trace cables are designed to economically and effectively provide heat to maintain water flow paths on eaves, in gutters, downspouts and drains. GutterMelt SR cables produce wattages of 5, 9, 12 and up to 24 watts per foot at 32° F in snow and ice These cables provide reliable freeze protection while carrying an industry leading 10 year warranty. GutterMelt is a great choice for either residential, commercial or industrial projects. Our Self Regulating technology is effectively used to heat trace pipes to keep fluids flowing.
