Build-In Strainer: Unlike regular push-button drains, this sink drain features an anti-clogging basket strainer that collects hair and prevents the drain from clogging. It also catches items like jewelry, rings, and dirt, preventing them from going down the drain. Two Mode Switch: The pop-up design replaces traditional inconvenient sink stoppers, such as basic plugs with chains. Simply press the top cap gently to switch between two modes: stopper (to hold water) and strainer (to drain water). 1.33-1.5 Inch Diameter: This bounce drain filter fits various types of pop-up filter basket drainers. It works with drain holes that have an inner diameter of 34mm - 38mm (1.33 - 1.5 in). High-quality Materials: The drain stopper is made primarily of durable stainless steel and brass, offering rust resistance, crack resistance, and a long lifespan. It provides strong bounce and rebound for quick sealing and draining with just one press. Easy Installation: To install, simply remove the old drain and insert the bounce core. Anyone can complete this process. The thickened and extended nut allows for easy hand installation without tools.
