Electric Roof Cable Kits help prevent roof damage by keeping melt water flowing through gutters and downspouts flowing even in frigid below zero temperatures. The package contains shingle clips and cable spacers, along with complete installation instructions. 120V, 5 Watts per foot. Length: 60 ft.
Run zigzags to create 15" wide triangles, running the cable from the overhang to the warm area of your roof. Secure the roof cable with brackets, affixed to each shingle where the roof cable bends. Run the end of the roof cable along the inside of your gutter and down the gutter's downspout. Plug it into a GFI outlet.
