Rain Bird 52SA Simple Adjust stainless-steel Gear Drive Rotor, Adjustable 40° to 360° Pattern, 25' to 50' Spray Distance. With its intuitive adjustments and impressive coverage uniformity, the Rain Bird 52SA gear drive 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. Quick check arc/fast forward feature allows you to check or set arc while sprinkler is running. 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. The protected closed-case design makes the 52SA ideal for “creeping” grasses, sandy soil and other harsh surroundings. Water-lubricated, gear-driven design provides long-lasting dependability; true 4" pop-up height clears taller grass. Dual-action, positive-stop wiper seal protects internal mechanisms from debris while assuring positive pop-up and retraction. Heavy-duty rubber encased cap helps protect against damage from edger strikes. O-rings and seals for extra protection in “gritty” water; and a self-adjusting stator that doesn't require replacement when changing nozzles. Rotor comes with a preinstalled 3.0 gallons per minute nozzle designed for a throw distance of 25' to 50 at common residential water pressure of 45-55 psi. Nozzle is easily removable and additional nozzles are available (Model# 4252NZLPK sold separately) to customize watering based on your specific flow rate and system requirements. 3/4" NPT female bottom threaded inlet.
