Nds 641 6 Inch Square Grate Low-profile Adapter

Product Description

The NDS 641 is a 6-inch square grate paired with a low-profile adapter, designed for surface drainage applications in residential and light commercial landscaping. This grate and adapter combination sits at or near grade level, collecting sheet flow and directing it into an underground drainage system. Licensed contractors and landscape irrigation professionals install this component as part of catch basin or channel drain assemblies where a low-profile inlet is required. Its square profile provides a clean, flush appearance while maintaining effective water intake.

This grate and adapter set is suited for use in yard drains, garden beds, lawn areas, and hardscape installations where a low-profile drainage inlet is needed. It integrates with standard 6-inch drainage systems and is appropriate for residential drainage projects, athletic fields, and similar light-duty surface water management applications.

Key Features

• 6-inch square grate profile fits standard drainage basin openings
• Low-profile adapter allows flush or near-flush installation at grade
• Suitable for residential and light commercial landscaping drainage

Compatibility

Designed as an OEM-style replacement or standard component for 6-inch square catch basin and surface drain assemblies in residential and light commercial drainage systems.

Installation Notes

Installation is typically performed by a licensed plumber, drainage contractor, or landscaping professional. Before servicing or replacing the grate, ensure the surrounding area is clear and the drainage basin below is free of debris. Follow local stormwater and grading codes when setting the adapter height relative to finished grade. Do not overtighten any fasteners securing the grate frame, as this may crack the adapter body.
