NDS 900BKITRTL1PK Square Catch Basin Kit – 9-Inch Grate, 2-Opening, Adapters & Plug for Lawns & Landscapes

Overview

The NDS 900BKITRTL1PK Square Kit combines essential drainage components into a compact, underground solution designed to capture stormwater runoff and route it toward a safe discharge point. This all-in-one setup helps keep surfaces like lawns, patios, and walkways clearer after rain while guiding water efficiently through the connected pipe network.

Why this kit can be useful

Intended for moderate stormwater flows, the kit supports properties where water tends to collect near edges or pathways. It features a 39.5 square inch open surface and a flow capacity that can move water downstream at up to 121 gallons per minute when installed properly. The durable plastic construction withstands outdoor conditions and the unit is ADA compliant in compatible configurations, offering a practical drainage option for accessible layouts.

• Capture and direct runoff on your property to help reduce surface pooling and edge erosion while protecting landscape features.
• Two side openings accept adapters for flexible piping configurations, enabling tailored drainage routes.

What’s included and how it fits your space

The kit includes a 2-opening catch basin, two outlet adapters, one plug, and a square plastic grate. Design details include keyed side openings for adapters, a bottom cutout guide for an additional keyed opening if needed, weephole knockouts to minimize standing water, and soil-tight outlet adapters to seal unused connections. The grate keeps debris from entering the pipeline while allowing water to pass.

• All major components needed for a complete drainage connection to typical 3 in. or 4 in. pipes are included.
• The debris-blocking grate helps maintain flow and reduces clog risks at the inlet.
