The steel sprinkler valve key is engineered for turning on and off or adjusting the flow of manual or automatic sprinkler valves which have a flow control mechanism. The prongs of the sprinkler valve key are spaced so that they fit over the handle of the valve and allow you to rotate it clockwise to reduce flow and counterclockwise to increase flow. The handle is both ergonomic and creates a way to hang the key for storage. Plated steel ensures long life of the key in a variety of weather conditions. The sprinkler key is available in 30 in. and 54 in.8 (sold in-store only) lengths to handle a variety of valve box depths. For outdoor irrigation use with cold water only.
