Compatible with 1.1" to 1.34" diameter drainage holes. After months of development, if the sink drain does not fit tightly, we include an additional large silicone ring along with the original to ensure a better fit for your drain holes. Note: Be sure to measure the drain holes of your sink before purchasing. Easy to Install The bathroom sink drain filter is simple to install—just remove the old one and insert the new. Anyone can complete the installation. To clean the drain plug, simply pull it up for easy maintenance. Upgrade Elastic Sink Stopper Compared to traditional rubber stoppers, our sink stopper offers easier drainage without needing to fully remove it. The one-button pop-up mechanism allows quick switching between sealed and drained positions in seconds. Built-in Filter The sink drain plug features an anti-clogging basket filter that effectively catches hair and debris, helping prevent blockages. It also keeps small items such as jewelry, rings, and dirt from falling into the drain. High-Quality Material Made from durable stainless steel and brass materials, this sink drain filter resists rust, cracking, and corrosion. Suitable for use in bathrooms, washbasins, bathtubs, and kitchens.
