Debris comes in all shapes and sizes, but the ones that fall from trees can be some of the most damaging to your drainage system. Overhanging branches can drop leaves, needles, and twigs that make their way from rooftop into the gutter downspout. Prevent them from entering and choking up your drain pipes by putting the 12 in. Downspout Defender™ Catch Basin Drain Grate in place. The 12 in. Downspout Defender Grate has a unique, patented design that captures more stormwater runoff than a traditional drain grate or drain cover. The grate has an angled face that minimizes splashing; water drains through while debris is deflected away and slides down the sloped surface into an easy-to-clean shelf. Made of high-density polyethylene (HDPE) treated with UV inhibitors
