The perfect choice for irrigation, dust control and watering large areas, this impact sprinkler slides over the top of standard metal T-posts (not included) for quick and easy setup. It sprays up to 90' in diameter, covering 6,361 square feet when set to a full circle. A simple twist of the diffuser screw breaks up the stream, creating larger or smaller water droplets. The flow-through outlet allows you to connect multiple sprinklers to expand watering areas, depending on water pressure. All-metal construction withstand high water pressures and severe weather conditions without the worry of breaking, rusting or failing.
