The 4” diam. funnel provided with this drain can be secured anywhere to the drain’s 8-1/2”, or 12” diam. strainer head to catch wastewater from above (an indirect connection) while the free area of the strainer serves the surrounding floor area. To simplify installation, the threaded strainer assembly rotates to the level of adjacent flooring after installation. The Duco coated cast iron drain has an integral collar that can be specified for use as a flashing clamp for a watertight seal with flooring materials and is available with down or side outlet.
