Raindrop's patented design combines details to provide the performance that you want under all weather conditions.
The round surface assures that surface adhesion directs water immediately into the gutter.
The tapered bar underside terminates the surface adhesion and increases its siphoning ability, for maximum water capacity.
Crossbars create up to five areas of precise water mass vs. volume ratio for an even balance of surface tension and capillary action. This is a vital aid in deterring water from "sheeting" over the gutter. The crossbars also promote increased water siphoning, surface durability, and provides organizational deterring of seedlings, leaf tips, stems, pine needles, and other clog forming debris.
