This utility drain is great for those oddball tub or sink applications where a finished, closeable drain is needed, but there’s no provision for overflow on the fixture. This drain stands 3 1/8″ tall, the top has a diameter of 2 15/16″, and the shank diameter is 1 7/8″. Best of all, the threads on the shank are 1 1/2″ pipe thread, so one can easily attach a waste line. Supplied with a suction cup to allow the user to easily open or close the drain. 4 finishes available, locknut is unfinished.
