From Clorox Commercial Solutions, the wall-mounted touchless Clorox Hand Sanitizer Dispenser provides a sanitary, easy-dispensing solution for high-traffic environments, like offices, reception areas, day care centers and schools. By automatically dispensing hand sanitizer, it helps your staff in their efforts to keep germs from spreading throughout these facilities. Using a sensor to recognize when hands are present in the dispensing area, the touchless dispenser automatically releases sanitizer. The dispenser unit comes with a wall mount kit and 4 C batteries which keep the unit running. When the batteries are low, a light indicates it's time to change them. The touchless dispenser works with the Clorox Hand Sanitizer 1 Liter Refill, which is sold separately.
