Rain Bird MPR-15CST center strip spray nozzle - rectangular pattern 1.2 x 9.2 m

Rain Bird MPR-15CST spray nozzle for long lawn strips

The Rain Bird MPR-15CST is a specialised center strip spray nozzle designed for automatic irrigation of long, narrow lawn areas. It produces a fixed rectangular spray pattern approximately 1.2 m wide and up to 9.2 m long. This makes it particularly suitable for narrow grass strips between garden paths, alongside patios or in elongated garden sections where conventional circular spray patterns may extend beyond the intended lawn area.

The distinguishing feature of the MPR-15CST is its central installation position. The sprinkler is installed in the middle of the rectangular lawn strip. From this position, the nozzle distributes water in both directions along the length of the strip, covering the lawn in front of and behind the sprinkler. This allows a long, narrow lawn area to be irrigated from a central position.

Rectangular spray coverage up to 1.2 x 9.2 m

The Rain Bird MPR-15CST features a fixed rectangular center strip spray pattern. Depending on operating pressure, it covers an area measuring approximately 1.2 x 7.9 to 1.2 x 9.2 m. At the optimum operating pressure of 2.1 bar, the maximum total length is 9.2 m. With the nozzle positioned centrally, coverage extends in both directions along the strip, reaching approximately 4.6 m in each direction when correctly aligned.

The spray trajectory is 30°. The integrated stainless steel adjustment screw allows the spray distance to be reduced to suit the length of the lawn strip. The rectangular spray pattern itself is fixed and cannot be changed to a different spray angle. For correct coverage, install the nozzle in the middle of the strip and align the spray pattern with its longitudinal axis.

Matched precipitation rates for balanced irrigation

The MPR-15CST belongs to the Rain Bird MPR Series. MPR stands for Matched Precipitation Rate and refers to coordinated precipitation rates across different nozzle patterns. The series includes conventional circular spray patterns and specialised strip patterns, allowing differently shaped lawn areas to be incorporated into an automatic irrigation system.

The Rain Bird MPR-15CST has a flow rate of approximately 3.4 to 4.6 litres per minute depending on operating pressure. At 2.1 bar, Rain Bird specifies a water consumption of approximately 270 litres per hour. Consider this value when planning your irrigation zone. Suitable operating pressure, correct sprinkler spacing and sufficient spray overlap are also important for consistent irrigation.

Easy installation on Rain Bird spray bodies

The Rain Bird MPR-15CST fits compatible Rain Bird spray bodies and suitable shrub adapters, including models from the Rain Bird 1800 Series. A white fine-mesh filter screen is supplied to help protect the nozzle from debris and maintain reliable operation. The integrated stainless steel adjustment screw allows the spray distance to be reduced during installation.

Rain Bird also offers other strip nozzles for different installation positions. The MPR-15EST is designed for installation at the midpoint of a short end of a lawn strip. The MPR-15SST is intended for a sprinkler positioned at the midpoint of a long side. The MPR-15LCS and MPR-15RCS provide specialised spray patterns for left and right corner positions. These alternatives help you choose the most suitable spray pattern for the shape and layout of your lawn.

Frequently asked questions about the Rain Bird MPR-15CST

What area does the Rain Bird MPR-15CST cover?

Depending on operating pressure, the nozzle covers a rectangular area approximately 1.2 x 7.9 to 1.2 x 9.2 m. At 2.1 bar, the maximum coverage is 1.2 x 9.2 m.

Where should the MPR-15CST be installed?

The nozzle should be installed in the middle of the rectangular lawn strip. From this position, it distributes water in both directions along the length of the strip.

Does the 9.2 m length refer to one direction?

No. The 9.2 m refers to the total length of the rectangular spray pattern. With central installation, coverage extends approximately 4.6 m in each direction.

How much water does the MPR-15CST use?

The flow rate ranges from approximately 3.4 to 4.6 l/min. At 2.1 bar, Rain Bird specifies approximately 270 litres per hour.

Can the rectangular spray pattern be adjusted?

The basic rectangular spray pattern is fixed. The spray distance can be reduced using the stainless steel adjustment screw, but the overall spray pattern remains unchanged.

Which sprinkler bodies are compatible?

The MPR-15CST fits compatible Rain Bird spray bodies and suitable shrub adapters, including models from the Rain Bird 1800 Series.

What is the difference between the MPR-15CST and MPR-15EST?
