Choosing the correct plate for your application:
- Plates are named after their nozzle size range (K1 - #8.3 / K2 - #9-10 / K3 - #11-12 / K4 - #13-14 / K5 - #15-16), and their trajectory (6°, 9°, 15°, or 24°).
- Low trajectory gives low stream height to avoid things like shade structures and vegetation, but also has the lowest radius of throw. Stream height and throw distance increase with trajectory.
- The colour band on the plate (white, black, or gray) matches the color of the sprinkler diffuser, which is designed with a specific number of "fingers" to provide optimum irrigation distribution uniformity.
