Lavatory sink drain, precision manufactured by <b>Hiendure</b>. <br> This drain is constructed from heavy, genuine stainless steel, and is exceptional quality. <br> This is a push-button style drain; simply press the top of the pop-up to close, and another press to open. <br> Inside the drain is a very-smooth, spring-loaded mechanism that maintains a water-tight seal without the need for a leaky push-pull lever. <br> This drain is "Overflow Style" for use with standard sinks and vanities that have an overflow hole at the top of the sink bowl. <br> Drain is standard-size; designed to fit bathroom, vessel and wet bar sinks, or any sink with a drain hole from 1 1/2" to 2" in diameter (fits almost all sinks). <br> The drain exit, or waste pipe, is standard 1 1/4" size, although these drains can also be used with 1 1/2" traps and a bushing. <br>
