Place the Guardian Counter-Mounted Eye Wash next to your sink and be prepared for emergencies in your lab. This eye wash station features a polished, chrome-plated brass arm that swings out over the sink for easy use; just push the hand lever down to activate water flow. The two spray heads have flip-top dust covers, internal flow control and water filters to remove impurities. Mount your eye wash unit on the left or right side of the sink with the included mounting hardware.
