The Bradley 6315-00 Automatic Lavatory-Mounted Soap Dispenser offers the convenience of hands-free soap dispensing, which helps maintain sanitary conditions in sinks used for hand-washing. Ideal for use in food service and medical settings, the dispenser can fit into any counter top with a hole that is 1 inch in diameter and that is a maximum of 2 inches thick. The spout is made from high-polished chrome-plated plastic and has an LED indicator light that blinks red when refilling of the soap is required and yellow when the battery is low. The automatic sensor is activated within 2 seconds. The motor is water resistant and operates with the attached battery pack that uses 4 alkaline D-cell batteries. In addition to purchasing the dispenser, you must also obtain a soap bottle to use with the unit. The motor is set for a 1,000-shot cartridge; however, it can be adjusted to accommodate 2,000 shot cartridges as well.
