12-Inch Square Catch Basin Drain Downspout Grate

Tree debris can clog your drainage system, but the Downspout Defender outdoor drainage grate is here to help. This unique grate is designed to stop leaves, needles, twigs, and other debris from entering your drain pipes. The patented design ensures that more stormwater runoff is captured compared to traditional flat water grates.

To use, simply place the grate on top of your 12 in. catch basin drain, with the angled face directing water away from the building. This prevents splashing and ensures that debris slides off the surface and settles into an easy-to-clean shelf. For added protection, consider using the Catch Basin Insert Filter (sold separately) inside your catch basin to block out fine particles.

Key features of the Downspout Defender include its ability to block tree debris from clogging your drainage system. It deflects leaves, needles, twigs, nuts, and seeds that fall from overhanging trees onto your roof and into your downspout, while capturing water into your catch basin or low-profile adapter.

Installation is simple - just place the grate on top of your 12 in. catch basin drain, riser, or low-profile adapter with the grate facing away from the building. Made of high-density polyethylene (HDPE) treated with UV inhibitors to prevent fading and cracking, this grate is designed to receive downspouts from 2 in. - 6 in. round or square, with a flow rate of 247 GPM.

Ensure the longevity and efficiency of your drainage system by investing in the Downspout Defender outdoor drainage grate. Say goodbye to clogged drains and protect your property from water damage caused by splashing downspouts. Trust NDS for all your stormwater management needs.
