These Chafer 20″ Multi-Rate Chafer Stream Bars are designed to fit Teejet/Spraying Systems nozzles spaced at 20″ across the boom (If your nozzle spacing is 15″ then you need to purchase 15″ stream bars).
The Chafer 20″ Multi-Rate Stream Bars feature a 6 position sliding orfice bar, which allow sprayers to apply a wide range of different rates (for example at 10 mph they will apply between 8 and 66 US gallons per acre of liquid nitrogen, when using all 6 of the adjustable settings).
These stream bars come with a rubber washer and a tip strainer (recommended even if you have in-line strainers).
IF YOU HAVE A CASE SPRAYER WITH AIM-COMMAND OR WILGER NOZZLES – YOU WILL NEED A WILGER ADAPTER FOR EACH STREAM BAR.
