The Crown produces a gentle sprinkling that both entertains children and cools your pool. One single nozzle produces a fan of softly falling fingers of water. In addition to visual delight, the Crown produces a backdrop of gentle, calming sound. Both the Stream Jet and Crown Jet have interchangeable heads. If you want a quick change of effect, you can simply unscrew the top and replace. Flush-mounted for pool walls, fans of water can arch up to 6 feet in height and work well in an array. Child safe when used as directed.
