ABSTRACT:
An arc marking system is provided for a sprinkler that waters an arc, either a full circle arc or a part circle arc. The system includes a plurality of arc indicators provided on the top of the nozzle assembly. Each arc indicator is adjacent an arc indicia such that each arc indicator represents a different arc that this sprinkler is capable of watering. After ascertaining the arc that a particular sprinkler can water, the arc information can be marked on the nozzle assembly by cutting off the arc indicator that is adjacent the numeral that represents the number of degrees covered by the arc. Thus, the arc information is added to the top of the sprinkler where it can be easily seen.
