Nelson Fixed Pattern Nozzles While many landscapes require precise fine-tuning to achieve optimum coverage, the vast majority of spray heads call for the use of standard angle nozzles...that is, fullcircle, half-circle, and quarter-circle patterns. When installing nozzles along straight runs or in areas that require 360° arcs, Nelson Fixed Pattern Nozzles will save labor by not requiring each nozzle be adjusted to these common patterns.
