The Expert Gardener, Q-series thumb control nozzles are made with a solid metal interior and a rubber over mold to provide both durability and comfort. They are constructed with high quality materials that can stand the test of time. The multi-pattern nozzle offers a choice of seven spray options to cover a variety of watering needs. The convenient thumb control knob allows you to easily adjust water flow and reduces hand fatigue. It also allows you to shut off the water without going back to the faucet, which helps conserve water. The handgrip is over-molded, not only to protect your hand from extreme water temperatures, but also to provide a comfortable grip.
