Garden sprinklers with moving parts have a tendency to give out after only one or two years of work. Not so with this solidly built, all metal professional sprinkler. Constructed from powder coated steel, copper tubing, and brass, it has a 20cm (7.75") spike that plunges into the ground, holding is stable and upright. At 152cm (60") tall, it waters a diameter of 22 feet. Operate at 25-30 PSI (standard household water pressure). Built to last a lifetime.
