6 in. Riser for 6 in. Round Spee-D® Catch Basin Drain

When your catch basin outlets deeper in the ground, use the 6 in. Riser for the Spee-D® catch basin drain to reach up and capture stormwater from the surface. The durable extension adds 2 in. to 6 in. to the top of the basin, eliminating the hassle of regrading or awkward piping; use cut guides to cut to size and easily get the height you need. The riser works with the 6 in. round Spee-D catch basin and is compatible with all drainage grates or drain covers that fit the Spee-D basin, such as the 6 in. round and square brass grates, 6 in. and 8 in. round plastic grates, 6 in. atrium plastic grate, 6 in. square grate and adapter, and 7 in., 8 in., and 9 in. square plastic grates. Made of high-impact polystyrene (HIPS) treated with UV inhibitors.
