GelMelt Calcium Chloride Melter
Use this revolutionary product to prevent Ice Dams. It is very easy to use and quickly and effectively carves a channel into ice and snow to allow the water to run off.
This is a 2 inch diameter by 16" long tube of gellified calcium chloride that you position perpendicular to the gutter, pointing up to the peak of the roof. It carves a deep, long channel so that the melt water runs off into the gutter. This can also fit into gutters. It is recommended to space a tube every 4 feet on the roof for optimal effect. This Gelmelt is long lasting and nearly impervious to rain.
