TabzTM provides a visual aide to orient flat "V" pattern sprays while the equipment is idle. The nozzles come in a variety of spray patterns, flow rates and spray angles, including Flat-V and Full Cone spray and are color-coded for each flow rate. They are compatible with thread-mounted nozzle designs as well as K-Ball R clip-on series of spray nozzles. The clip-on feature simplifies your plumbing as no tapping of holes is needed. Single or dual retention clips allow spraying pressures up to 150 psi.
