The JR SMITH 2005y04ba-p050 is a 4-inch adjustable cast iron floor drain designed for commercial and residential plumbing installations where reliable floor-level drainage is required. The round top measures 5 inches across with an overall top size of 9 inches, and the adjustable body allows for precise height setting during concrete pours or finish floor work. It includes an integrated strainer and a trap primer connection, making it compatible with trap primer supply lines that maintain the water seal in the drain trap. Licensed plumbers install this drain as part of wet-area and utility floor drainage systems.
This drain is suited for shower rooms, toilet rooms, and kitchen areas where floor drainage is required by code. The trap primer connection port makes it appropriate for installations where the drain may experience infrequent use and trap evaporation is a concern, such as mechanical rooms, commercial kitchens, and restroom floors. The adjustable body accommodates variations in finished floor thickness, giving installers flexibility during rough-in and finish stages of construction.
Designed as an OEM-style floor drain for 4-inch drain pipe connections in residential and commercial plumbing systems requiring a round adjustable floor drain with trap primer capability.
Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and verify drain line routing before setting the drain body in the slab form or existing floor opening. The adjustable collar should be set to finished floor height before concrete is poured or tile is set to ensure a flush, properly sloped finish. Do not overtighten the strainer or locking ring components during final assembly.
