Chrome-plated, solid brass face & eyewash unit is designed to fit laboratory gooseneck faucets as a permanent face wash & eyewash fountain with unlimited water supply in an emergency. In operation, unit mounts to the spout with two spray nozzles curving upwards with a 15 degree greater angle then the standard OK-II model. In an emergency, it frees both hands to hold eyes open to the flow of water. Delivering more than 3 gallons of water per minute, it does so at a reasonable height. No plumbing required. Two of the most common adapters are packed with the unit.
