Tapmaster knee activators are designed to be installed behind a cabinet door or drawer. All you have to do to turn the water on is press against the door or other face and voilà! Water on!

Of all the Tapmaster activator styles, knee/cabinet door activators are the simplest to install and most cost-effective. The Tapmaster turns the entire cabinet door into an activation surface. Many customers report that our cabinet door activators are simplest to use just by leaning against the cabinet when they want water.
