    Features

    The SRM is Hunter’s shortest-range rotor, and was designed to offer a convenient and efficient alternative to spray heads. It is capable of working in tandem with larger rotors to combine big and small areas in a single zone. Utilizing the SRM where appropriate results in fewer sprinklers performing more efficient work at a more economical price. The SRM features a rack of six water-efficient nozzles—all of which can be easily identified by their flow rates and installed and changed quickly and easily. This versatile rotor also includes a radius adjustment feature that fine-tunes the spray to keep water off driveways, walks, and other non-landscaped surfaces.

    Key Benefits

    Adjustable arc from 40° to 360° to keep water in the appropriate areas
    Standard factory-installed 2.0 nozzle speeds installation
    Through-the-top arc adjustment for easy installation
    QuickCheck™ arc mechanism for fast Arc Adjustment
