Product Review

Square Drain Riser & Plug replaces the round "Riser" or "Inlet" portion of these drains.  In most cases this simply requires the round "Riser" or "inlet" portion of the drain to be removed and replaced by the E4400. If the fit is too loose to create good thread engagement Teflon plumbers tape can be used to build up the E4400 to a larger diameter as needed to create a snug fit.
