Freeze Free self-regulating pipe heating cables provide flexible protection against pipe freeze-ups;Cut-to-length capability on the job is ideal for installations that require protection of numerous pipes of varied lengths;The self-regulating effect of the cable reduces power consumption when the pipe does not require freeze protection;Increases Watts per foot the colder it gets and decreases when the temperature gets warmer;Braided metal jacket provides an electrical ground as well as protection against damage in dry locations;Cables are rated at 3 Watts per foot (0.30 m), +50F (+10C) - 75 ft (22.86 m) maximum circuit length;Can be wrapped over itself (overlapped), if necessary, when installed on pipes, valves or flanges
