Marking flags are used to indicate the location of sprinkler heads, valves, drains, and other equipment. They are especially useful when laying out valve and head placement in an irrigation system but are also handy for marketing the location of heads when conducting audits, repairs, and lawn aerations. They are 15 in. tall and are constructed from medium gauge steel wire with vinyl flags imprinted with the Orbit logo. Each bundle of ten flags comes one color per bundle. White, red, blue, yellow, or orange selected at random upon fulfillment.
