Flo-Free Leaf Guard is the only true gutter filter system that allows water to flow, while keeping the gutters clean for a lifetime. Flo-Free is installed with new or existing 5K and 6K gutters to eliminate ice dams, leaf dams and water damage. Unlike covers, this filter system allows full use of the gutter opening and allows absolutely no runoff. For more information, call DCI Products Inc. at 800-622-4455 or visit www.dciproducts.com.
