NDS Drainage Grates

Our Square grates and adapters are a perfect fit when the need for a catch basin is not necessary.

Connect these grates directly to pipe or fittings. Round grates to fit 3" to 15" sizes of sewer and drain pipe, corrugated pipe, or triple-wall pipe. Our Atrium grates are ideal for areas with no traffic where debris like mulch and leaves might clog a flat grate. Our most heavy-duty grates, DuraCast In-Line grates are 6" to 12" wide to fit corrugated pipe or sewer and drain pipe. NDS has a wide variety of brass and chrome grates for projects where quality and aesthetics are a must.
