Rain Bird® UNI-Sprays and VAN Nozzles ensure the diverse needs of your landscape, including oddly shaped corners, will be evenly watered, leaving you with a beautiful lawn and garden. UNI-Sprays are ideal for smaller grassy areas around sidewalks and driveways; they can also be used for watering flowerbeds or shrubs. The UNI-Spray's compact design makes these sprinklers less noticeable when not in operation, so relax and enjoy your landscape.

* Uni-Spray does not come with a nozzle unless specified in the options*

For added convenience, these reliable, compact spray heads can be shipped with or without pre-installed Variable Arc Nozzles (VANs) that are adjustable from 0° to full circle operation, saving hours of installation time, effort and money.
