Set includes 50' of hose, 3 rotor sprinklers, 3 end caps, 1 hose coupler and 1 Y-connector. Use scissors to cut the hose to the lengths you need, then attach sprinklers. Waters 400 square feet. Y-Connector provides additional opportunity to customize your system. You can create two watering zones or create a loop for more even water flow across all sprinklers.
