This gutter brush set is designed to help keep standard 5-inch gutters clear by blocking leaves, pine needles, acorns, and other debris while allowing water to flow freely. The brush features medium-density polypropylene bristles with a heavy-duty galvanized steel wire core for durability and flexibility. Its slide-in design allows quick, tool-free installation and easy cleaning. The brush can also be bent or trimmed to better fit different gutter shapes and hard-to-reach areas. Ideal for year-round gutter protection in a variety of climates.
