Guardian's Counter-Mounted AutoFlow Eye Wash is a convenient, space-saving way to respond quickly to chemical exposure. This eye wash system mounts next to your sink and features two spray heads on the swinging arm; simply move the arm over the sink to activate water flow. Move the unit back to the storage position to close the valve and turn off the water. Each spray head has a flip-top dust cover, internal flow control and filter to remove impurities. Mount your eye wash system on either the left side or right side of the sink. Comes with mounting hardware.
