Rain Bird GRC111022 Acme 751 Series Golf Rotor with #22 60psi Nozzle with Rapid-Adjust Technology let your staff make easy arc adjustments with the turn of a screw. MemoryArc retains two part-circle arc settings, so you can shift between full and part-circle operation in seconds. For golf course superintendents and their crews, efficiently irrigating around obstacles, on slopes and in windy weather can be a real challenge. The low angle nozzle housing can enhance distribution uniformity under these tough conditions. Offering proven Rain Bird durability and distribution uniformity, these cost-efficient rotors are also backward-compatible with existing Rain Bird rotor cases. Doing more when it matters most. That’s The Intelligent Use of Water.
