Rain Bird U-10H dual-orifice spray nozzle - 180° half-circle - 2.1 to 3.1 m radius

Rain Bird U-10H dual-orifice nozzle for lawn borders

The Rain Bird U-10H is a high-efficiency dual-orifice spray nozzle with a fixed 180° half-circle spray pattern and a radius of 2.1 to 3.1 m. It is particularly suitable for automatic lawn irrigation along straight property boundaries, garden paths and patios. Its semicircular spray pattern directs water to one side of the sprinkler, providing targeted irrigation for lawn edges and landscaped borders.

As part of the Rain Bird U-Series, the U-10H features two separate spray openings. These distribute water both close to the sprinkler head and across the outer watering area, supporting more uniform coverage throughout the half-circle spray pattern.

180° half-circle coverage for straight lawn edges

With its fixed 180° spray angle, the Rain Bird U-10H is designed for sprinklers positioned along straight lawn boundaries. It is especially useful where grass meets a patio, wall, walkway or garden bed. The half-circle spray pattern helps direct water onto the intended lawn area while minimizing unnecessary watering behind the sprinkler.

The spray radius ranges from 2.1 to 3.1 m depending on operating pressure. At the optimum pressure of 2.1 bar, the nozzle achieves a radius of approximately 3.1 m. Its 12° spray trajectory supports controlled water distribution. The integrated stainless steel adjustment screw allows the radius to be reduced when required.

Dual-orifice technology for improved close-in watering

The distinguishing feature of the Rain Bird U-10H is its dual-orifice design. The main opening distributes water toward the outer edge of the semicircular spray pattern, while the additional opening delivers water directly around the sprinkler head. This helps address uneven watering close to the sprinkler, where conventional spray nozzles may leave dry patches.

The improved distribution supports consistent irrigation along lawn borders. According to Rain Bird, U-Series nozzles can reduce water consumption by up to 30% compared with conventional spray nozzles under suitable installation conditions. Actual savings depend on system design, water pressure and irrigation scheduling.

Easy installation on Rain Bird spray bodies

The Rain Bird U-10H is compatible with Rain Bird spray bodies and suitable shrub adapters, including pop-up sprinklers from the Rain Bird 1800 Series. A fine mesh filter screen helps prevent debris from entering the lower spray opening.

For installations with higher supply pressure, a pressure-regulated spray body can help maintain nozzle performance close to the recommended pressure. When planning your irrigation system, position sprinklers to provide sufficient overlap between adjacent spray patterns. The U-10H can be combined with suitable U-10Q quarter-circle and U-10F full-circle nozzles to cover corners, edges and interior lawn sections.

Frequently asked questions about the Rain Bird U-10H

What is the spray radius of the Rain Bird U-10H?

The spray radius ranges from 2.1 to 3.1 m depending on operating pressure. At 2.1 bar, the nozzle reaches approximately 3.1 m.

Can the 180° spray angle be adjusted?

No. The U-10H has a fixed half-circle spray pattern. Quarter-circle and full-circle models are available separately.

How much water does the U-10H use?

The flow rate is approximately 2.2 to 3.1 l/min, equivalent to around 132 to 186 litres per hour, depending on pressure.

Why does the nozzle have two spray openings?

The additional opening delivers water close to the sprinkler head, helping improve uniform coverage and reduce dry patches around the spray body.

Which sprinkler bodies are compatible?

The Rain Bird U-10H is compatible with Rain Bird spray bodies and suitable shrub adapters, including models from the Rain Bird 1800 Series.

Can the U-10H be combined with other U10 nozzles?

Yes. The U-10H can be combined with appropriately selected U-10Q quarter-circle and U-10F full-circle nozzles. Their different flow rates must be considered when designing the irrigation zone.
