Page 1 This invention relates to a fire-fighting water nozzle. It is a hollow steel tube which is pointed to facilitate penetration of doors, walls and panels. The pointed end of the tube is perforated with drilled holes to allow water to be projected from the pointed end of the tube, the holes being so arranged to provide maximum coverage by the water spray. The opposite end of the tube is flanged and threaded to accommadate the common 1? inch fire hose coupling. A high-impact plastic cap is placed over the flanged (threaded)end of the tube to allow the tube to be driven (with the use of a hammer) through partitions walls, etc. without damage to the hosecoupling threads.
