About the Rainbird IF4PCSS Falcon Adjustable Circle Rotor
Rainbird IF4PCSS Falcon Adjustable Circle Rotor. The Rain Bird IF4PCSS is an International model 6504 Series Falcon Part-Circle Rotor Pop-Up Sprinkler with Stainless Steel Shaft. It features easy arc adjustment through the top of the rotor from 40 - 360-degrees with no tools required, a water-lubricated gear drive for reliable rotation, a standard black rubber cover, a removable Seal-A-Matic check device to prevent puddling and erosion caused by low-head drainage, a self-adjusting stator that doesn't require replacement when changing nozzles, and a patented pressure-activated wiper seal and tapered riser stem on both plastic and stainless steel models to protect internals from any debris to ensure positive pop-up and retraction.
