Its patented angled design efficiently captures up to 247 gallons per minute of stormwater while deflecting tree debris like leaves and twigs to prevent clogs. Lightweight and easy to install, it also minimizes splashback to protect your property walls, making it a must-have for professional-grade outdoor drainage solutions. ## Description 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. When overhanging branches drop leaves, needles, and twigs that make their way down from the roof to your gutter downspout, let the Downspout Defender outdoor drainage grate stop them in their tracks before they can enter and choke up your drain pipes.The downspout drain grate features a unique patented design that captures more stormwater runoff than a traditional flat water grate. Made to fit on top of your 12 in. catch basin drain, the grate has an angled face, with the high end closing the distance the water drops from the downspout, preventing water from splashing against the building wall or ricocheting off the grate surface. The debris that hits the grate automatically slides off the sloped surface and settles into an easy-to-clean shelf. Combine with the Catch Basin Insert Filter [sold separately] inside your catch basin to block out fine particles for a smooth-running drainage system.NDS offers free tools such as the Home Drainage Center, Calculators, and NDS Stormwater Drainage mobile app to help make your project a success.

Review: Great product, sheds leaves and drains lots of water! - Great product that performs much better than the previous gutter drainage design I had. Made it through TS Beta (>12” rain locally in 24 hrs) without issue!! My previous gutter drainage was a 3x4 Fernco fitting straight to 4” SDR pipe. The problems I had with that arrangement were that small amount of leaves would clog the fitting, or a tee downstream, and backup the water which would in turn soak my exterior home wall. I removed the Fernco fitting and cut the piping back to allow installation of a NDS 12” Basin Extension, of which I concreted the bottom. I then had to remove my downspout and modify its projection off the wall about 1.5” in order to fit the slope of the drain grate. I then fit up the downspout to overhang the top of grate by about 1-2” to prevent splash back onto the house during heavy rainfall scenarios. This setup so far has been through Tropical Storm Beta (I’m in Houston), and performed beautifully! Review: Ideal for downspout drain box. - Excellent quality. Sturdy. Well made. Just what I needed in windy rainy Florida. It replaced the lid that came with the 12" drain basin which drains to a buried pipe system. It did need longer stainless screws than what were supplied. The lizards love it. They like to hide inside and peek out the slats. ## Features - BLOCKS TREE DEBRIS FROM CLOGGING YOUR DRAINAGE SYSTEM: Protects your drainage system by deflecting leaves, needles, twigs, nuts, and seeds that travel from overhanging trees onto your rooftop and into your downspout, while capturing water into your catch basin or low-profile adapter - HOW TO USE: Drains excess stormwater from under downspouts into a capture device such as a catch basin or low-profile adapter; must-have for downspouts carrying tree debris from rooftops - HOW TO INSTALL: Place on top of the 12 in. catch basin drain, riser, or low-profile adapter with grate facing away from the building - DESIGN FEATURES: Patented design captures more water than traditional flat drain grates; angled face allows debris to slide off the surface; reduces downspout splashing to protect property walls - SPECIFICATIONS: Made of high-density polyethylene (HDPE) treated with UV inhibitors to prevent fading and cracking; 54.5 sq. in. open surface area; receives downspouts from 2 in. - 6 in. round or square; 247 GPM flow rate ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07DJZVNHL | | Additional Features | Lightweight | | Best Sellers Rank | #34,976 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1,052 in Pipe Fittings | | Brand | NDS | | Brand Name | NDS | | Color | Black | | Compatible Groove Diameter | 12 Inches | | Compatible groove diameter | 12 Inches | | Customer Reviews | 4.6 out of 5 stars 110 Reviews | | Finish Type | Matte | | Finish Types | Matte | | Fits Hole Size | 12 Inches | | Included Components | NDS - 1200DSG | | Item Depth | 11.75 Inches | | Item Type Name | NDS - 1200DSG | | Item Weight | 0.5 Pounds | | Manufacturer | NDS | | Manufacturer Part Number | NDS - 1200DSG | | Manufacturer Warranty Description | 1 year warranty. | | Material | Plastic | | Material Type | Plastic | | Model Number | NDS - 1200DSG | | Number of Items | 1 | | Special Feature | Lightweight | | UPC | 052063055688 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** NDS - **Color:** Black - **Material:** Plastic - **Finish Type:** Matte - **Special Feature:** Lightweight ## Images ![1200DSG Square Catch Basin Drain Downspout Grate, Fits 12-Inch Square Catch Basin Drain, Riser, or Low-Profile Adapter, 12-Inch, Plastic, Black - Image 1](https://m.media-amazon.com/images/I/71-JPvhb8mL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product, sheds leaves and drains lots of water! *by C***Y on September 29, 2020* Great product that performs much better than the previous gutter drainage design I had.
