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.
