HUNTER I-20 ULTRA ROTARY SPRINKLER:

The Hunter I-20 Ultra is your one-stop-shop for sprinkler rotors. With the ability to cover a radius range from 18 to 47 feet, you now have the choice to use only one sprinkler compared to having a variety of rotors and sprays.

If you're looking to upgrade over a typical residential grade irrigation rotor, this is where the search ends. No other irrigation rotor in its class gives you more. Like easy arc adjustment right at the top of the irrigation sprinkler, a heavy duty spring with reliable retraction, and a standard water-saving drain check valve that handles up to 10 feet of elevation change. Plus, the Hunter I-20 Ultra Rotor includes a rack of nozzles with both standard and low angle nozzles (the ideal solution for virtually any landscape situation), as well as the new FloStop(TM) feature that provides the added convenience of easily stopping water flow through a single sprinkler head without turning off the entire irrigation system. With its ultra-sturdy construction, rest assured you've got a product that's sure to endure - it's even protected by a full five-year warranty! But, for those who still want more, be sure to consider our stainless steel option.
