The Duplex low-pressure impact sprinkler is designed with a heavy-duty cast aluminum body, brass drive lever, and brass lower turning connection. Features include adjustable stops for full or partial circle coverage, an adjustable jet breaker to change the flow pattern, and a quick-change nozzle setup supported by a 2-inch standard pipe thread connection. Duplex is a dual-port sprinkler with a secondary flow nozzle directly above the main barrel to cover close and medium ranges. Duplex is unique among most impact units because the drive lever operates from the secondary nozzle, not the main riser. This allows the main riser to project water and achieve maximum distance breaks from the drive lever. The Duplex low-pressure impact sprinkler also has a slightly slower reverse motion than most traditional impact sprinklers and performs well at lower pressures. Includes a nozzle kit that provides 42 to 174 gallons per minute and covers up to 280 feet in diameter! Specifications Flow range: 42-174 gal/min.
