The Vevor gutter brush is designed to help keep 5-inch gutters clear by blocking leaves, pine needles, acorns, and other debris while allowing rainwater to flow freely. Its polypropylene bristles and galvanized steel wire core provide year-round performance in a variety of weather conditions. The flexible brush design can be adjusted to fit corners and trimmed as needed for different installations. This 27-piece set provides 80' of total coverage and installs easily without tools.
