uses two laws of physics, surface adhesion & gravity, to effectively convert existing rain gutters into self-cleaning gutters.
has no openings on top so gravity does not work against it.  The only openings are the two rows of offset filtering louvers on the vertical face of the panels. This is where surface adhesion comes into play, drawing the rain water into the gutters, even in the hardest rain.
offset louvers on the vertical face keep leaves, pine needles, etc. from washing into the gutters when it rains.
