NDS 1200DSG Square Catch Basin Drain Downspout Grate, Fits 12-Inch Square Catch Basin Drain, Riser, or Low-Profile Adapter, 12-Inch, Plastic, Black

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!

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.

Was having a continual problem with the drain until this purchase. It is a great solution if you have leaves that clog your drain.

Just what I needed for fall

I have this at the end of a downspout that collects the water from 3 converging gutters. The volume of water makes for a lot of exit velocity and this catch basin is perfectly designed for the situation. It's nice a rigid even while being pounded by the outpour. The grates are a good size to allow for lots of water to enter but not leaves.

This thing is a pretty nice addition to our drainage system. I thought it sounded nifty, but considered it kind of a "nice to have" item. Now that it's installed and been through a few heavy rains, I consider it a "need to have" for my remaining projects. This thing works well to keep downspout water away from walls and foundations, while catching larger solids (catkins, twigs, leaves). The catch basin filter sock is working well to keep shingle granules out of the system overall.

Does a great job keeping leaves out of my yard drains

These are sturdy catch boxes designed to filter out leaves and debris from rain gutter flow. That avoids clogging the drains too quickly. They are a bit pricey though.
