The Wedge is the only "self-cleaning" rain gutter filter in the industry and the most effective way to keep rain gutter downspouts clear of leaves and debris.
The Wedge's revolutionary new patented "flow thru" design allows water to flow thru top, bottom, both sides and back, increasing drainage by 2000% over conventional rain gutter drain filters! The top sloped grid prevents messy clogging by forcing leaves and debris to float up and away from the drainspout opening, thus allowing more water to flow thru unhindered.
