When debris falls into the gutter downspout it can quickly infiltrate the drainage system and potentially clog the pipeline. But not if you protect it properly. There’s no better way to block leaves, needles, twigs, and other particles that fall from overhanging tree branches onto the rooftop and down the downspout than with the 9 in. Square Downspout Defender Kit. The unique, patent-pending grate closes the distance water falls from the downspout to prevent water splashing against walls; debris is blocked by the grate and slides down the sloped surface into the tray. The low-profile adapter is ideal in spaces where the depth of a traditional catch basin won’t fit. Kit includes a 9 in. Downspout Defender grate made of high-density polyethylene (HDPE), low-profile adapter made of high-impact polystyrene (HIPS), and outlet adapter to connect to 3 in. & 4 in. sewer and drain, single-wall corrugated, triple-wall, and DWV/Sch. 40 pipes.
