Product Description:
This contractor-grade nozzle is constructed out of powder-coated metal for added durability and extended life with a ridged rubber handgrip for a comfortable hold. The adjustable nozzle offers a high-flow design, which gives you 20% more water flow than similar designs, and easily adjusts from a light spray to a powerful jet spray. The thumb control lever allows you to turn on/off the water and modify the water pressure from the nozzle without going back to the faucet
