ABSTRACT:
The invention is an improvement in a disc and a handle for the receiver section of a fire fighting nozzle. Together, this disc and handle facilitate the opening and closing of a fire nozzle assembly, for permitting and preventing, respectively, the discharge of fire extinguishing fluids from that nozzle. The improvement of the present invention results from the use of a one-piece disc with generally resilient arms, and from the use of a plastic handle with a generally oblong shaped slot.
