Spec Sheet

From the company that invented the first impact sprinkler, the 2045PJ Maxi-Bird is a rugged, high performance 1/2 inch riser mounted impact head that is ideal for watering slopes and large areas. Offering both full and part-circle operation and Rain Bird's unique Precision Jet tube design, the Maxi-Bird helps you save water and keep landscapes lush and green.

Designed for a variety of uses where full circle sprinklers should not overthrow water into restricted areas. The body, arm, bearing sleeve and nipple are made of durable Delrin™ plastic.
  • 1/2 in. (15/21) riser-mounted impact head used for slope and large-area, above-grade applications
  • Straight-through flow for superior performance in dirty water
  • Proven impact drive for maximum reliability
  • Double-weighted arm for slower rotation and increased distance of throw. Powerful reverse action.
  • Adjustable arm spring for low-pressure and low-gallonage operation
  • Precision Jet tube (PJ™) minimizes side splash
  • FP trip permits full- or part-circle operation (20° to 340°)
  • Interchangeable, color-coded bayonet mount nozzles
  • No tools required to change nozzles
  • Includes blue #08 standard angle nozzle preinstalled.
