Protect high-capacity gutters from clogs and overflow with the GutterBrush Simple Gutter Guard, made in the USA and trusted since 2004. This GutterBrush gutter guard is designed for homes and structures with oversized 6 in. gutters. Installation is fast and simple-no tools, cutting, screws or fasteners. GutterBrush works differently than flat screens and covers. The brush fills the gutter space to help prevent debris from collecting into a clogging dam, while water continues to move through open pathways to the downspout. Built with UV-protected polypropylene bristles twisted around a 12-gauge galvanized steel core, it flexes to fit common gutter styles and can be removed anytime for quick maintenance-lift out, shake clean and reinstall.
