The Nelson Fireman's nozzle is designed with heavy duty, die-cast zinc with a large metal shutoff handle and Grip-Guard overmold. This heavy duty construction allows for the toughest cleaning jobs and withstands up to 250 psi. The fireman's style lever allows for easy and convenient adjustable spray flow. A simple backwards pull of the fireman's style lever turns the water on and controls the amount of water flowing through the nozzle. To turn the water off, simpy push the lever forward.
