What is the difference between GutterMelt sold by the foot and GutterMelt kits?

GutterMelt sold per foot is bulk cable cut to the length specified for the project, intended for custom installation by a contractor or electrician. GutterMelt kits are pre-configured, ready-to-install cordsets that come factory-terminated with a 6-foot power cord and LED plug, along with downspout hangers and roof clips, in standard lengths from 10 to 130 linear feet. The kit format trades custom sizing for plug-and-play simplicity — ideal for straightforward residential installations.
