Fill gutters end to end with GutterBrush. (Packs include 36 in. and 18 in. lengths) Bend around corners and if piece is too long, simply fold the brush back into itself to fit. No tools or need to cut.
Most leaves will pass over the rounded GutterBrush profile. Small debris caught in the top of the brush blows away or breaks down into small particles and washes through the gutter during natural weather cycles.
