DUAL USE: STOPPER OR DRAINAGE WITH HAIR CATCHER: press the central chrome button to open it and allow the water to flow out and use it as a hair catcher thanks to these small vertical bars that block the hair. Or flip the raised edges down to completely block off your shower or tub drain. EASY TO INSTALL AND MAINTAIN: is easy to install in any tub; simply place it over your tub or shower drain and you’re ready to go; fits most standard tub and shower drains; simply wipe or rinse with mild soap to clean. SIPHON PLUG WITH HAIR CATCHER: Say goodbye to clogged shower drains and non-working tub stoppers. With the filter plug you prevent hair from clogging your siphon and you prevent odors from rising, by closing it with a simple pressure. Once inserted into your bathtub drain, simply press the center to convert it to a hair catcher or back to a bathtub stopper.
