[ Universal Size ] Pop up sink plugs can be used with various types of pop-up filter basket drains. Includes three built-in rubber rings that can be adjusted to fit drain holes with an inner diameter of 28-58mm. [ Upgraded Design ] This bathroom sink strainer is more convenient and functional than a standard sink stopper. The upgraded stainless steel push-button drain stopper features an anti-clogging basket to help prevent hair and debris from clogging the drain. Comes with a non-slip rubber pad and two rubber rings (large and small) to prevent leaks. [ Easy Installation ] The pop-up sink drain stopper is simple to install with no tools required. Just remove the old stopper and insert the new one. For larger drain holes, use the included rubber ring to adjust the fit. [ High-Quality Materials ] Made from durable zinc alloy, this drain stopper is rust-resistant, crack-resistant, and built to last. The strong spring mechanism ensures quick water drainage and reliable sealing. [ Secure Fit ] The rubber ring around the basket provides stability and prevents tilting when pressed. A large non-slip pad under the spring core ensures a tight seal with the sink drain under water pressure, ensuring effective drainage and leak-free performance.
