Features & Benefits

ain Bird UNI-Sprays 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.

The UNI-Spray accepts all Rain Bird nozzles, including MPR, VAN and U-Series, making it an excellent choice for watering standard and irregular-shaped turf and shrub areas. 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.

  • Pressure-activated, wiper seal prevents excessive flow-by and water waste. Keeps debris from entering upon retraction.
  • Durable stem ratchet allows for quick and easy nozzle pattern alignment.
  • Internal parts are removable from the top of the sprinkler for easy servicing.
  • Small exposed cover makes the unit virtually invisible for more attractive landscapes.
  • Rugged cover and body provide durability in high pressure and surge conditions.
  • Plastic and stainless steel materials resist corrosion.
  • Available in 4-inch (10,2 cm) models to provide unobstructed watering of today's taller turf grass varieties.
  • VAN nozzle and screen are easily removable for flushing.
  • UNI-Spray accepts all Rain Bird Series nozzles and accessories, which simplifies inventory management.
