Products / GutterBrush Brush Gutter Guard

A brush gutter guard with a galvanized steel wire core and thick, UV-protected bristles, slid into the gutter in 3-foot sections with no tools or fasteners so it fills the whole trough. The maker sells it by actual brush diameter: 2.25 inches (sold as the Channel Flow Guard for small channels, manufactured homes and similar), 3.25 inches for 4 inch gutters, 4.25 inches for standard 5 inch K-style gutters, 5.25 inches for 6 inch gutters, and 6.5 and 8.0 inches for commercial, metal building and pole barn gutters. Its Channel Flow Guard page says that size is the same product, only smaller. The product pages say it is made in the USA and carries a 10-year material warranty.
