adjustable from straight stream to a dense fog pattern.
The Task Force Tips Masterstream Series Nozzles automatic nozzles operate by sensing the pressure at the nozzle inlet and adjusting
the discharge opening to maintain a constant pressure throughout the flow range of the nozzle. While flowing, the stream pattern can be
varied from wide fog to straight stream. Trapped debris can be removed without the use of tools.
