These nozzles are among the most common and best known in ornamental fountain designs.
They have a spherical joint that allows you to obtain parabolic jets with a vertical inclination of 20º, or vertical jets that can be animated by varying their height, and stopping and starting rhythmically. Outlet diameters of 4 to 10mm are suitable for indoor use, while for outdoor are most suitable outlet diameters of 10 to 30mm.

Some nozzles allow reaching great heights in external fountains or lakes, when you want the jet to be visible from a great distance.
