Simply slide one end of the brush into the existing gutter, and you're all set. Suitable for various settings such as homes, gardens, and fish ponds. Year-Round Gutter Protection For Any Climate: The gutter brush is made with professional-grade polypropylene bristles and a heavy-duty galvanized steel wire core. It can withstand various natural elements without rusting or corroding, regardless of the season or climate. Designed for 5-Inch Gutters: The gutter brush has a diameter of 4.33 inches to better fit standard 5-inch (12.7 cm) gutters. The flexible bristles can be easily trimmed according to actual needs, and adjusting the shape won't affect the roof structure. Quick and Efficient: Gutter Cleaner fits most standard gutters and easily reaches difficult areas, and ensuring a thorough cleaning saving save you time and effort.
