SR31J250 Sr Trace 250 Ft Spool

Easy Heat Sr31j250 250ft Self

A special self-regulating core is at the center of the SR Trace cable. This core is conductive and adjusts according to the surrounding temperatures. When it is cold, the cable s core has many conductive paths that generate enough heat to keep the water flowing from the roof to the ground. As the surrounding temperature warms, there are fewer conductive paths and less heat is generated.
