Product Overview

Drain the excess stormwater away, not the leaves and debris in it. The 9 in. Square Drain Grate blocks troublesome particles from entering and potentially clogging your drain pipes, while letting the stormwater flow through. Use the drain grate (also known as a drain cover) to drain moderate flows from lawns, landscaped areas, patios, walkways, and under downspouts. The 9 in. square drain grate has an open surface area of 28.4 sq. in. and a flow rate of 87 GPM. Connects to the Spee-D® Catch Basin Drain, 6 in. sewer and drain pipe & fittings, 6 in. single-wall corrugated pipe, and 6 in. Sch. 40 pipe for a soil-tight fit. The pipe grate is ADA Compliant. Built to stand up to the elements, it’s made of polyethylene, a type of plastic, using a combination of virgin and recycled content treated with UV inhibitors to prevent fading and cracking from the sun. As part of a complete drainage system, the grate drains water while preventing leaves and debris from entering the drain pipes. The pipes carry the water to a discharge point downstream such as a pop-up emitter, or to percolate into the ground with a dry well or infiltration trench. Start now and find the right drainage grate for your project with the free NDS Home Drainage Center tool at ndspro.com/home-drainage.

Answers

The catch basin can be beneficial if there is a lot of debris on the roof, maybe from trees. The grate will filter out much of the larger debris and prevent it from going down the drain line.

Can it be drove on by a lawn mower

Asked by Danny June 26, 2016

Answers

You could drive over it with a lawn mower, but I would either disengage the blade or make sure your drain cover is secured and would not be sucked up by the wind tunnel.

what size drainage pipe does this attach to?

Asked by george June 26, 2015

Answers

It doesn't. This is a grate that goes with a 9 x 9 basin purchased separately. Those basins have openings for both 4 & 6 inch corrugated pipe.

As far as plastic drainage grates go, this one is top notch! When looking to purchase a plastic drainage gate I was a little intimidated and concerned as I had never purchased a plastic drainage grate before. However this product has completely met the expectations I had for a plastic drainage grate!
