Plan the right fit before choosing
Select a part designed for the application
Different drain locations call for different component styles. Sink options include flat strainers, basket drain assemblies, flange assemblies, a brass drain, a lever-handle bushing, and an overflow head assembly. Floor drain and floor sink choices include drop-in and dome-style strainers. A cast iron dome is specified for a compatible roof drain membrane clamp.
- Flat sink strainers are available for compatible 3-inch and 3-1/2-inch sink openings.
- The plastic drop-in strainer fits compatible small floor drains and is described as a secondary strainer beneath the floor drain.
- The white dome strainer is intended for floor sink drain areas.
- The cast iron replacement dome is for an RD2190 universal membrane clamp.
Use stated sizes to narrow compatible choices
Opening diameter is a primary selection factor for sink components. Also compare the outside diameter or flange size where provided, as well as NPS, MPT, or tailpiece connection details for drain assemblies.
- Compatible sink opening sizes represented include 1-7/8 to 2 inches, 3 inches, 3-1/2 inches, and dual 3-inch or 3-1/2-inch applications.

- One stainless steel sink drain assembly includes a rubber stopper for closing the sink drain when needed.
- Listed installation components on selected items include gaskets, locknuts, washers, a coupling nut, and a flanged washer.
