New and Improved Profile louvered aluminum guards for 5in gutter are made by E-Z Gutter, the leader in gutter protection. Since 1983, E-ZGutter has been engineering innovative designs for every type of gutter and debris load. E-Z-Shield Gutter Guards are a snap to install. No screws are needed. Each section is notched for 3/4in in overlap. The heavy-duty painted aluminum won’t rust or rot. Designed to stay put during rough weather, the guards easily snap out for maintenance. Patented louvers allow maximum water flow through the cover, but still keeps out debris. The black color is attractive as it visually blends with the roofline, but more importantly, it absorbs solar heat to expedite melting of snow and ice. Each box of guards will cover 39.25ft of gutter.
