NDS 900GRKIT 9 in. Square Catch Basin Kit with Green Grate

The NDS 900GRKIT 9 in. Square Catch Basin Kit is a complete drainage solution for yards, driveways, patios, and light-duty hardscape areas. The kit pairs a UV-stable, injection-molded polypropylene basin with a green square grate and includes locking outlet adapters and a sealing plug for reliable, soil-tight connections.

• Kit contents: one 9 in. x 9 in. tapered catch basin with built-in sump, one 9 in. square green plastic grate, two locking outlet adapters (for 3 in. and 4 in. lines), and one outlet plug.
• Durable construction: UV-stable polypropylene resists fading, corrosion, and cracking; lightweight for fast handling yet strong enough for Class B loading when installed correctly.
• Compatibility: Works with 3 in. & 4 in. sewer and drain pipe, single-wall corrugated, triple-wall, and Schedule 40/DWV pipe using the included locking adapters for a soil-tight connection.
• Performance: 39.5 sq. in. open grate area with up to 121 GPM flow (9 in. grate); built-in sump traps sediment and debris to help prevent downstream clogging.
• Traffic rating: Class B — suitable for pedestrian traffic, autos and light trucks when installed per manufacturer's guidelines; not intended for heavy commercial loads.
• Maintenance: Grate lifts easily for inspection and cleaning; remove debris from the sump periodically and reseat the plug as needed to maintain proper flow.

Designed for simple installation and low upkeep, the 900GRKIT streamlines surface-water management and erosion control in residential and light-commercial projects. The included adapters and plug let you connect directly to common 3–4 in. drainage piping for a neat, long-lasting installation.
