Protek's Adjustable Flow-Baffle Monitor Nozzles are combination pattern, master stream nozzles with selectable flow settings. Flow is adjusted by a simple press-turn motion of the outer spring loaded baffle and rotating to the laser etched position for the desired flow. Nozzles must be shut down to change settings. The nozzles have excellent straight stream performance and a wide, dense, fully adjustable fog pattern. All nozzles are compatible with Protek's wide range of monitors.
