Rain Bird 52SA Simple Adjust Stainless-Steel Gear Drive Rotor 25' - 50' With its intuitive adjustments and impressive coverage uniformity, the rotor will water all areas of your lawn evenly; reducing water use and providing greener, healthier grass. The many safeguards and trouble-free features built into our closed-case rotor sprinkler make it the perfect choice for any home landscape. Easily adjusts at the top with a flat blade screwdriver from 40 to 360 part-circle arc rotation, and reversing full-circle rotation to ensure you're watering only things that grow, not the house, sidewalk, or driveway. For installation convenience arc rotation is factory preset at 180. Rain Bird's patented industry-leading Rain Curtain? nozzle technology delivers a uniform, rotating curtain of large water droplets that fall exactly where you want and resist windblown overspray. The nozzle's "micro ramps" also direct a portion of the spray close to the head eliminating dry brown spots common with other rotor brands. The nozzle's superior coverage uniformity helps reduce watering time saving money on water bills. Top-of-the line rugged design with stainless steel shaft for a longer life.
