Product Overview
The DSR-RGS-12 roof and gutter self-regulating heat-trace cable helps prevent ice dam and icicle formation on building roofs and in gutter systems during freezing conditions. It adjusts its heat output according to the surrounding temperature, ensuring effective melting of snow and ice only where required. Typical installations include: along roof edges, in valleys, inside gutters, and through downspouts to maintain continuous water flow and prevent blockages that can lead to roof leaks, structural damage, or safety hazards from falling ice. These cables are widely used in residential, commercial, and industrial buildings where reliable winter freeze protection is essential.

Key Features
-
Self-regulating technology – cable output increases in cold conditions and decreases as it gets warmer, reducing power consumption while maintaining protection.
-
Safe to overlap and cut to length in the field, thanks to its self-modulating behavior that prevents overheating.
-
Robust cable construction with a semi-conductive polymer core, insulation, optional tinned-copper braid for grounding, and a UV-resistant thermoplastic elastomer outer jacket.
-
UV-resistant design for roof and gutter applications exposed to sunlight.
-
Reliable freeze protection for roofs, gutters, and downspouts in a wide range of building types.
Typical Applications
-
Roof edges
-
Roof valleys
-
Inside gutters
-
Through downspouts
Used to maintain continuous water flow and prevent ice-related blockages, roof leaks, structural damage, and hazards from falling ice on residential, commercial, and industrial buildings.
