Leaf Defier 6'' Half Round Gutter Insert

Half-round gutters are the traditional gutter style for many, especially those with homes that were built before the advent of K-style gutters in the 1950s. The Leaf Defier is an open cell polyurethane insert, specially shaped and cut to fit snugly into your spouting. Even during the heaviest of rainstorms, the water flows through the Leaf Defier into the spouting valley and out the downpipe. Leaves and debris slide off the surface or just dry up and blow away. Your gutters will remain clean and clear of clogs. The Leaf Defier's patent pending material is factory treated with a biocide and fungicide that inhibits the growth of mould, mildew, fungus, algae and moss. It also has a built in UV stabilizer to prevent degradation from the sun.
