NDS 6 in. Riser for 9 in. Square Catch Basin Drain and Low-Profile Adapter Drain

Need to capture excess surface water with a catch basin that runs deeper underground? No problem. The 9 in. Square Catch Basin Riser adds up to 6 in. of height to your catch basin, eliminating the hassle of regrading or awkward piping.

The 9x9 catch basin riser fits the 9 in. square catch basin drain and low-profile adapter, and accommodates a 9 in. catch basin drain grate, also known as a drain cover, on top. It's made of high-impact polystyrene (HIPS) treated with UV inhibitors, and can be cut to size with a saw to fit your project needs. Hassle-free limited lifetime warranty guarantees the NDS product is free from defects—or we'll replace it.
