Why does GutterMelt sold per foot carry a longer warranty than the kit version?

GutterMelt cable sold per foot carries a 10-year manufacturer’s warranty. Pre-configured cordset kits carry a 5-year warranty. The difference comes from the kit’s added components — the factory termination and LED plug — which have a shorter rated service life than the heating cable itself. The cable in both versions is identical; the warranty difference reflects the additional hardware required to make the kit plug-and-play.
