The Melnor QuickConnect System makes switching watering tools fast and easy. The 5-Piece Starter Set prepares both ends of your hose for the QuickConnect system and includes adapters for your faucet and two watering tools. The Product Adapters stay in place on your nozzles, wands, or sprinklers so you can quickly connect and disconnect tools. You can even change tools while the water is running. Put one Product Adapter in your watering wand to water your hanging baskets and add one to your favorite adjustable nozzle to spray a larger area. Make an easy switch between the two tools without going back to the faucet to turn off the water. The locking feature keeps tools connected and prevents unintentional disconnection while watering. A must-have for multi-tasking, the Melnor QuickConnect System makes connections easy.
