4″ Round Atrium Grate

A robust round, domed drain manufactured from a structurally foamed High Density Polyethylene (HDPE) with a UV inhibitor to reduce sun damage. This grate is designed with large opening slots for maximum flow while still preventing large debris from entering the drainage system. Precision engineered and manufactured to attach directly to Sewer and Drain Pipe and Fittings, Triple Wall Pipe and Corrugated Pipe.

APPLICATIONS

A domed grate that is typically used for medium sized areas of flower beds that are mulched. Grate connects directly to drainage pipe without the need for a catch basin. Excess water flows towards and through the grate and then drains directly to below grade drainage pipe that allows the water to flow to areas where excess water can be tolerated. This style of grate is not recommended for any areas exposed to traffic. The domed or atrium style is designed to prevent mulch or debris from plugging the grate openings.
