Nds 1216 Catch Basin Riser 6 in Black 12 in Series

Product Description

The NDS 1216 is a 6-inch black catch basin riser designed to increase the depth of a 12-inch catch basin installation. This open-bottom extension fits into an existing 12-inch catch basin assembly, allowing contractors and drainage installers to add height to the basin stack when site grade or soil depth requires it. The riser is molded in black and integrates directly with the NDS 12-inch catch basin series. Licensed drainage installers and landscaping contractors typically specify this component during storm water and surface drainage system builds.

This riser is intended for use in residential and light commercial drainage applications where additional basin depth is needed to meet finished grade requirements. It is commonly installed in yard drains, parking area drainage systems, and other surface water collection configurations. Because there is no bottom on this unit, it functions solely as a vertical extension piece within a catch basin assembly, not as a standalone collection point. It is sold individually and packaged in units of 8 per case.

Key Features

• 6-inch height extension for 12-inch catch basin assemblies
• Open-bottom design allows stacking within existing basin series
• Black molded finish suited for below-grade and at-grade installs
• Compatible with the NDS 12-inch catch basin series
• Sold per each, packaged 8 units per case

Compatibility

Designed for use with the NDS 12-inch catch basin series. This riser is not a standalone unit and must be paired with the appropriate NDS 12-inch base and grate components.

Installation Notes

Installation of catch basin risers is typically performed by licensed drainage or irrigation contractors following applicable local stormwater and grading codes. Before adding or modifying basin depth, ensure all upstream flow is diverted and excavation is stable. Stack risers only with compatible basin base components and verify the final assembly is level and properly bedded before backfilling. Do not use this riser as a standalone catch point without a properly seated base unit.
