The PULSE Pop-Up Drain is easy to use and provides a convenient way to control the amount of water in a sink or bathtub. When the Pop-Up Drain is raised, water can flow freely through the drain, and when it is lowered, the stopper seals the drain to prevent water from draining out. Made of brass and plated in your desired finish, the Pop-Up Drain is universal in size and is and can be opened and closed with a central toe-tap.
