This heating cable protects pipes, roofs and gutter systems from damage due to freezing and can be used in residential and light commercial applications. The self-regulating freeze protection cable automatically adjusts its heat output according to the ambient temperature conditions. Under cooler conditions, the heat output increases, and as the temperature rises, the output decreases to save on energy. MANUFACTURING:- Normal cable width 0.42 in.
