A Gardena swivel nozzle is ideal for spraying rectangular surfaces. If you are looking for a sprinkler for circular surfaces, look at the Gardena circle sprinklers. If you want a sprinkler for all garden contours, check out the Gardena multi-sprinklers. Do not forget that you need a hose piece (with or without water stop) to connect your Gardena swivel nozzle to your garden hose. See also the other Gardena products.
