Rain Bird SQ-FUL square pattern spray nozzle - full pattern 360° - two throw distances of 0.8 and 1.2 m

Rain Bird SQ-FUL for small planting areas

The Rain Bird SQ-FUL is a pressure-compensating spray nozzle featuring a full square pattern for automatic irrigation of small planting areas. It is particularly suitable for flower beds, perennials, groundcover and densely planted garden sections. Unlike conventional 360° spray nozzles, the SQ-FUL does not produce circular coverage. Instead, it creates a complete square spray pattern with straight outer edges, helping direct water towards the boundaries of rectangular planting areas.

The nozzle is installed within the area to be irrigated, preferably in the centre. From this position, it distributes water in all four directions and reaches the corners of the square coverage area. This makes the SQ-FUL particularly useful for small planting beds where consistent water distribution is required and overspray beyond the planting area should be minimised.

Two selectable throw distances of 0.8 and 1.2 m

The Rain Bird SQ-FUL combines two preset throw distances in a single nozzle. By rotating the nozzle to the next indexed position, you can switch between 0.8 and 1.2 m. The shorter setting produces a nominal square coverage area of approximately 1.6 x 1.6 m. The longer setting provides coverage of approximately 2.4 x 2.4 m. The throw distance is measured from the centrally positioned nozzle towards the boundary of the spray pattern.

Actual throw depends on operating pressure and installation height. At higher pressures, Rain Bird specifies distances of approximately 0.9 or 1.4 m. Switching between the two settings is performed directly at the nozzle without additional tools. This allows you to adapt the SQ-FUL to differently sized planting areas without replacing the nozzle.

Pressure compensation for precise micro irrigation

The SQ-FUL belongs to the Rain Bird SQ Series, developed for targeted irrigation of small garden areas. Its integrated pressure compensation supports controlled water delivery across the specified operating pressure range. The square spray pattern distributes water towards the corners of the planting area. With suitable system design, this can reduce the number of spray nozzles required.

The operating pressure range is 1.4 to 3.5 bar. According to Rain Bird's performance chart, the SQ-FUL uses approximately 76 litres per hour at 1.4 bar and 92 litres per hour at 2.1 bar. At higher pressures, consumption increases to approximately 103 litres per hour. Both throw settings deliver the same flow at a given pressure. Since the irrigated area changes, the different precipitation rates should be considered when designing an irrigation system.

Flexible installation and reliable operation

The Rain Bird SQ-FUL is compatible with several Rain Bird spray bodies and adapters, including the Rain Bird 1800 Series, UNI-Spray, Xeri-Pop and suitable PolyFlex riser adapters. This allows the nozzle to be installed close to ground level or raised above surrounding plants. Correct installation height helps prevent foliage and other obstacles from interfering with the square spray pattern.

A blue fine-mesh filter screen is supplied to protect the nozzle openings from debris and support reliable operation. Rain Bird specifies a minimum filtration requirement of 40 mesh. For other coverage requirements, the SQ Series includes the SQ-QTR for square quarter patterns and the SQ-HLF for rectangular half patterns. These alternatives allow you to choose suitable spray patterns for different planting areas.

Frequently asked questions about the Rain Bird SQ-FUL

What area does the SQ-FUL cover?

The SQ-FUL produces a complete square spray pattern. At its nominal throw settings, it covers approximately 1.6 x 1.6 m or 2.4 x 2.4 m. Actual coverage depends on operating pressure.

How do I switch between the two throw distances?

Rotate the nozzle to the next indexed position to switch between the 0.8 and 1.2 m throw settings.

Where should the SQ-FUL be installed?

The nozzle should be installed within the planting area, preferably in the centre. From this position, it distributes water in all four directions to create a square spray pattern.

How much water does the SQ-FUL use?

According to Rain Bird's performance chart, the flow rate ranges from approximately 76 to 103 litres per hour. At 2.1 bar, consumption is approximately 92 l/h.

How does the SQ-FUL differ from a conventional 360° spray nozzle?

A conventional 360° nozzle produces a circular spray pattern. The SQ-FUL creates square coverage with straight outer edges, making it especially suitable for small rectangular planting areas.

Which Rain Bird spray bodies are compatible?

The SQ-FUL is compatible with Rain Bird 1800 Series spray bodies, UNI-Spray, Xeri-Pop and suitable riser adapters.

Can I combine SQ-FUL, SQ-HLF and SQ-QTR nozzles?

Yes. These models belong to the Rain Bird SQ Series and provide coordinated spray patterns for different planting area shapes. Consider their different flow rates and selected throw settings when designing your irrigation system.
