Abstract: A fire-fighting hose nozzle or line nozzle, that is, a nozzle used to discharge fluid spray during fire-fighting operations, is accoutered for high water-pressure spraying of water or other fire fighting fluid by professional firefighters. Such a high-pressure can, for instance, put about 200 pounds (p.s.i.) or more pressure on a nozzle tip. The nozzle has a long, slender body member with a weighted and pointed tip, a discharge orifice at a position rearward of the pointed tip, and at least one transverse member, and in embodiments a plurality of transverse members. The transverse member most proximate to the proximal end of the body member functions both as a set of handles and as a stabilizing member. A second transverse member functions as a stabilizing member. The orifice is a slot angle-cut forward or backward from its mid-section which produces a wide and high fan-shaped spray in either the forward or backward direction.
