Let your drainage system do its job effortlessly without leaves and debris bogging it down.

The 6 in round grate connects to the 6 in Spee-D® catch basin, 6 in sewer and drain pipe and fittings and 6 in single-wall corrugated pipe for a soil-tight fit. Made of high-density polyethylene (HDPE) treated with UV inhibitors.
